College Physics 2.65 - Velocity graph of a world-class sprinter

A graph of v(t) is shown for a world-class track sprinter in a 100-m race. (a) What is his average velocity for the first 4 s? (b) What is his instantaneous velocity at t=5 s? (c) What is his average acceleration between 0 and 4 s? (d) What is his time

A graph of v(t) is shown for a world-class track sprinter in a 100-m race. (See Figure 2.67). (a) What is his average velocity for the first 4 s? (b) What is his instantaneous velocity at t=5 s? (c) What is his average acceleration between 0 and 4 s? (d) What is his time for the race? Figure 2.67 Solution: Part A

To find for the average velocity over the…
