Problem 38PE

A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 11.5 m/s and accelerates at the rate of 0.500 m/s2 for 7.00 s. (a) What is his final velocity? (b) The racer continues at this velocity to the finish line. If he was 300 m from the finish line when he started to accelerate, how much time did he save? (c) One other racer was 5.00 m ahead when the winner started to accelerate, but he was unable to accelerate, and traveled at 11.8 m/s until the finish line. How far ahead of him (in meters and in seconds) did the winner finish?

Step-by-Step Solution:

Step-by-step solution 38PE Step 1 of 7 The formula for final velocity from equation of motion is, Here, u is the initial ve locity, is the final ve locity, is the acceleration and t is time the racer takes to reach final velocity.
