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 ▼Part 1 Your...

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...

The drag racer P starts from rest at the start line S and then accelerates along the track. When it has traveled 112 m, its speed is 50 m/s and it is accelerating forward at 10.0 m/s2. For that instant, determine the values of r and θ relative to axes fixed to an observer o in the grandstand G as shown. 歇一 36 m 0

1) The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.23 rad/s2. It accelerates for 22.7 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 57.7 s after it begins rotating. Hint:This is rotational motion, with equations for angles similar to those for linear motion. Note that the TOTAL time is given. Answer: ______ deg. 2) A proposed space station includes living quarters in...

A car starts from rest, and begins accelerating at a constant rate a1. It accelerates at this rate from a distance of 56.9 m from its starting point, and then immediately begins to decelerate at a different constant rate a2, eventually coming to rest again after traveling an additional distance of 79.4 m from where it began decelerating. the entire tripfrom start to finish(starting and ending at rest) lasts for a duration of 19.1 s. a)what is the magnitude of...
