QUESTION:
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?

ANSWER:
Problem 38PE
Solution 38 P
Step 1of 9:
In this question, we need to find final velocity
With the data
Initial velocity
Acceleration
Time taken
In the second part we need to find time saved by the rider, considering final velocity from previous section
Data given
Distance
In the third part, we need to find the distance travelled by the winner from other rider
Data given
Initial distance from winner
Velocity
