Sean is running a 100 m dash. When the starter's pistol fires, he leaves the starting block and continues speeding up until 6 s into the race, when he reaches his top speed of 11 m/s. He holds this speed for 2 s; then his speed has slowed to 10 m/s by the time he crosses the finish line 11 s after he started the race 11) Chapter 2, Problem 6 Assume that Sean starts from rest and his motion...

A sprinter in a 100m race accelerates from rest at a rate of 5.0m/s^2. She maintains this acceleration for a period of 6.0s. Once she has reached her top speed, she continues to run at her top speed for the rest of the race. Q. calculate the total time take for the sprinter to run the 100m race. - how do I get the time while accelerating and time while at constant velocity? Could you please explain how EASY and...

Chapter 2, Problem 2/084 Multistep A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 39 km/h at the 68-m mark. He then maintains this speed for the next 66 meters before uniformly slowing to a final speed of 34 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Finish line 39.9 m â–¼Part 1 Your...

12) A sprinter running a 100 m race starts at rest and accelerates at constant acceleration A for 3.0 seconds and then maintains a constant velocity. In terms of A, what is the position of the runner after 3.0 seconds? What is A if the sprinter finishes the race in 12.0 seconds? 13) What force is needed to accelerate a 30.0 lb block at 2.2 m/s2? 14) What force is needed to stop a 1500 kg car in 40 m...
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
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 10.8 m/s in 2.54 s, what will be his total time?
