A race-car prototype, is being testing for how quick will it attain an optimum velocityof 51.3m/s completely from rest. The car is also expected to maintain the 51.3m/s velocitythereafter.a. Given than the target constant acceleration is 50.34 ms⁄ 2 from 0 to 51.3m/s, how quickwill it reach 1200km if the 51.3m/s, maintained during the initial acceleration? {Hint:divide the solution into two parts, during the initial acceleration + during constantspeed. Steps are: 1) Solve for the time span during the acceleration phase, 2) Solve forthe total distance travelled during initial acceleration, 3) determine the remainingdistance to be covered at constant speed, 4) solve for the total time to cover #3, 5) addthe results of 3 and 5}. b. What must be the of acceleration of the car during the initial burst if it was able to reach100m in just 3 seconds?
In 2008, at the Beijing Olympics, Usain Bolt of Jamaica reclaimed his title as the world's fastest man. He completed the l00m final in a world record time of 9.69 s. He accelerated uniformly from rest for the first 6.5 seconds, covering 60 m before coasting at maximum speed to the finish. Calculate his average speed for the first 6.5 s.
I need answer asap. Tysm! A car starts from rest with an acceleration of 6.8 m/s2 which decreases linearly with time to zero in 9.1 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 360 m from the start.

A bicyclist is practicing to increase his endurance for a one-hour trip. He has an average speed of 30 m/s in the first 30 min. If the cyclist wants an average speed of 40 m/s for the entire trip, by how much does he need to increase his average speed in the last 30 minutes?
A runner is moving with a speed of 2.68[m/s]. How long will it take the runner to complete a 5.0[km] race? Express your answer in seconds. Ignore the time it takes to reach this speed, and assume the runner is always at this speed.
A sprinter starts from rest and accelerates to her maximum speed of 9.7 m / s in a distance of 9.7 m. What was her acceleration,if you assume it to be constant? And if this maximum speed is maintained for another 91.8 m how long does it take her to run 101.5 m?
A train of has a maximum speed of 50 km/hr and its acceleration and deceleration are limited to a maximum rate of 2.222 m/s^2. How much time does it take for the train to accelerate and achieve its maximum speed and then decelerate to a halt?
A tortoise can run with a speed of 0.15 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 1.0 minutes. The tortoise wins by a shell (25 cm). How long does the race take? (sec) What is the length of the race?(m)
A car starting from rest moves with a constant acceleration of 10km/ℎ?^2 for 1 hour, then decelerates at a constant -5 km/ℎ?^ 2 until it comes to a stop. How far has it traveled in meters.
During an auto accident, the vehicle's air bags deploy and slow down the passengers more gently than if they had hit the windshield or steering wheel. According to safety standards, the bags produce a maximum acceleration of 60g, but lasting for only 40 ms (or less). How far does a person travel in coming to a complete stop in 40 ms at a constant acceleration of 60g? (Express your answer in meters.)
If a car has zero acceleration must it’s velocity also be zero? Explain.
