Problem 81CP

A sprinter can accelerate with constant acceleration for 4.0 s before reaching top speed. He can run the 100-meter dash in 10.0 s. What is his speed as he crosses the finish Une?

Step-by-Step Solution:

Solution 81CP

Step 1 of 4:

We are going to find the speed of the sprinter when he finishes the line.

The total time taken by the player t = 10 s

The total distance x = 100 m

The time duration of the constant acceleration t1 = 4 s

The initial speed vi = 0

The starting point of the race x0 = 0
