A 66.0 kg sprinter starts a race with an acceleration of 1.88 m/s2. If the sprinter accelerates at that rate for 28 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race?
1. An 84.0 kg sprinter starts a race with an acceleration of 1.44 m/s2. If the sprinter accelerates at that rate for 41 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race? 2. (a) If the rocket sled shown in the figure below starts with only one rocket burning, what is the magnitude of its acceleration (in m/s2)? Assume that the mass of the system is 2090...
An 87.0 kg sprinter starts a race with an acceleration of 2.28 m/s^2. If the sprinter accelerates at that rate for 30 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race?
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...

Item 17 A sprinter runs a 100 m dash in 12.0 s. She starts from rest with a constant acceleration ay for 2.6 s and then runs with constant speed for the remainder of the race. Part A What is the value of ar? Express your answer with the appropriate units. μΑ ? ay = Value Units Submit Request Answer
A sprinter explodes out of the starting block with an acceleration of +2.48 m/s2, which she sustains for 1.44 s. Then, her acceleration drops to zero for the rest of the race. What is her velocity at (a)t = 1.44 s and (b) at the end of the race?
A sprinter explodes out of the starting block with an acceleration of +2.34 m/s2, which she sustains for 1.26 s. Then, her acceleration drops to zero for the rest of the race. What is her velocity at (a)t = 1.26 s and (b) at the end of the race?
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?
