A sprinter accelerates from rest to a top speed with an acceleration whose magnitude is 3.78m/s2. After achieving top speed, he runs the remainder of the race without speeding up or slowing down. The total race is fifty meters long. If the total race is run in 8.38 s, how far does he run during the acceleration phase?
One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.1 m/s in 2.54 s, what will be his total time?
a runner, from rest, in a 150m race accelerates uniformly for the first 23m then runs with constant velocity. If the runner's time for the first 23m is 5.4 seconds. what is:1. acceleration? 2. final velocity? 3. time on the race?
A car with initial velocity 7.2 m/s undergoes a constant acceleration. What is the acceleration (in m/s2 ) if the velocity of the car is 9.5 m/s 6 seconds later? Make sure to include a minus sign, if appropriate.

In a 100-rn race, the winner is timed at 11.2 s. The second-place finisher’s time Is 11.6 s. How far Is the second-place finisher behind the winner when she crosses the finish line? Assume the velocity of each runner is constant throughout the race.
a parachutist opens his chute at time t=0, while falling vertically at a speed of 50.0 m/s. From the combined effects of gravity and air resistance, he is subject to anupward acceleration of ay= (40/T)e-t/T where T=6.8s. Find the parachutist's speed 10s after the chute is opened and the distance fallen during that period of time.
a motorist travelling with a constant velocity of 30m/s passes school- crossing comer, where the speed limit 20km/h. just as the motorist passes, a traffic officer on a motorcycle stopped at the comer starts off in pursuit with a constant acceleration of 2.0m/s^2. how much time elapsed (in seconds) before the officer catches up with the motorist.
An object starts from rest and moves along the a axis such that for the first 10 seconds, itsposition is given by x = 2t^3 + 3t in meters. After that, it continues with a constant velocityfor 5 seconds. It then speeds down with a constant deceleration of magnitude 5 m/s? andcomes to a complete stop.(a) Find the instantaneous velocity and acceleration at t = 10.(b) Find the total displacement of the object.
