What is a race car’s average acceleration if its speed changes from 0 m/s to 40 m/s in 4 seconds?

Average acceleration of the car is 3m/s^2 Average acceleration is change in velocity divided by time taken or a=(v-u)/t, where u is initial velocity, v is final velocity and t is time taken. As such average acceleration of the car is (15-0)/5=15/5=3 m/s^ Average acceleration is change in speed over total time. In other words, average acc = (Vf - Vo) / t. For your first question: (36 - 2) / 4 = 34/4 = 8.5m/s^2. For your second, you must rearrange the equation as follows with algebra: a * t = Vf - Vo. Vf = Vo + a*t. Tadah, a simple and commonly used kinematics equation

Example 1: If your car starts at 0 mph and accelerates to 60 miles per hour in 8 seconds, what is its average acceleration during these eight seconds? The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared There is a simple equation in the suvat set of 5 equations. You only have to choose the right equation, plug in the data, and do the algebra to solve for the acceleration. Kinematics - SUVAT equations (worksheets, videos, solutions, examples, acti..

Answer: There are two steps to this problem: finding the acceleration and then the distance. The distance covered is 160 m. First use the formula v = u + at to calculate the acceleration. The initial velocity, u, is 0 ms^-1, and we are given the final velocity v = 40 ms^-1 and the time taken, t=8s. Rearranging, a = v/t = 40/8 = 5ms^-2 To find the distance travelled, use the formula d = ut + 1/2at^2.

Speed at the rev limiter estimated by Car and Driver. With the rev-limiter raised to 8,300rpm, the XP5 prototype was able to reach an average top-speed of 386.7 km/h (240.3 mph). No tested top speed faster than 340 km/h (211 mph) found for an unmodified car. 2005 Bugatti Veyron EB 16.4: 408.47 km/h (253.81 mph

second in 4.0 seconds. The magnitude of the car's acceleration is A) 40. m/s2 B) 20. m/s2 C) 5.0 m/s2 D) 10. m/s2 ___ 14) The diagram below represents the relationship between velocity and time of travel for four cars, A, B, C, and D, in straight-line motion. Which car has the greatest acceleration during the time interval 10. seconds to 15. 16b. A spacecraft traveling at a speed of +1,210 m/s is uniformly accelerated at the rate of -150 m/s^2. If acceleration lasts for 1.8 seconds, what is the final speed of the craft? DISPLACEMENT DURING UNIFORM ACCELERATION: d = [(vf + vi) / 2] t 17. A race car starts from rest (Vi = 0) and is accelerated uniformly to +40 m/s in 8.0 seconds. mine the student's acceleration. A car increases its speed from 9.6 meters per second to 11.2 meters per second in 4.0 seconds. !e average acceleration of the car during this 4-second interval is 1. 20.40 m/s 2. 2.4 m/s2 3. 2.8 m/s 4.D. 5.2 m/s 15. As a car is driven south in a straight line with decreas-ing speed, the acceleration of the car. A race car is traveling around a race at an average speed of 65.625 m /s (147 mph). The race car takes 2 minutes and 44 seconds to go around the track once. (A) What is the centripetal acceleration of the car? (B) Is the car WEIGHS 7840 N, then what is the centripetal force acting on the car a. if forward is the positive direction, a car moving backward at decreasing speed b. in the same coordinate system, a car moving backward at increasing speed c. a car that is moving on a circular track at a constant speed $16:(5 a. if forward is the positive direction, a car moving backward at decreasing speed

A racing car traveling with constant acceleration

1) A car with an intial speed of 23.7 km/hr accelerates at a uniform rate of 0.92 m/s2 for 3.6 sec. Find the final speed and displacement of the car during this time. Vi= 23.7 km/hr = 23700 m/3600 sec = 6.583 m/s=V This is bad. Looking at the above graph, you would be over 28 g's for about 0.04 seconds. Note to self. Don't crash your car into a wall if you are going 70 mph even if the car has a huge spring.

28 m/s — 0.0 5.5 m/s2 = s A car slows from 22 m/s to 3.0 m/s at a constant rate of 2.1 m/s2. How many seconds are required before the car is traveling at 3.0 m/s? = + at so t = 3.0 m/s — 22 m/s —2.1 m/s2 = 9.0 s e Use Figure 3-11 to determine the velocity of an airplane that is speeding up at each of the following times. 80 78 76 a, 74 72. 20. A car traveling in a straight line has a velocity of +5.0 m/s at some instant. After 4.0 s, its velocity is +8.0 m/s. What is the car's average acceleration during the 4.0-s time interval? 21. A certain car is capable of accelerating at a rate of +0.60 m/s2. How long does it take for this car to go from a speed of 55 mi/h to a speed of 60. mine the student's acceleration. 14. A car increases its speed from 9.6 meters per second to 11.2 meters per second in 4.0 seconds. The average acceleration of the car during this 4-second interval is 1. 0.40 m/s2 2. 22.4 m/s 3. 22.8 m/s 4. 5.2 m/s2 15. As a car is driven south in a straight line with decreas-ing speed, the acceleration of.

+7.5 m/s2 for 4.5 s. How fast will it be going at the end of that time? 19. A race car starts from rest and is accelerated unformly to +41 m/s in 8.0 s. What is the car's displacement? 20. A jet plane traveling at +88 m/s lands on a runway and comes to rest in 11 s. a. Calculate its uniform acceleration. b. Calculate the distance it travels. The definition of acceleration Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr final speed = 100 km/h of 12.5 minutes. What is the person's average speed? Answer: 4.29 m/s b. What is the person's average velocity? Answer: 0 m/s 14. (G13) A sports car accelerates from rest to 95 km/hr in 6.2 seconds. What is its average acceleration in m/s2? Answer: 4.3 m/s2 15. (G15) A sprinter accelerates from rest to 10.0 m/s in 1.35 s. What is her.
