Problem 24P

A world-class sprinter can burst out of the blocks to essentially top speed (of about 11.5 m/s) in the first 15.0 m of the race. What is the average acceleration of this sprinter, and how long does it take her to reach that speed?

Step-by-Step Solution:

Solution 24P

Step 1 of 3:

In this question, we need to find the average acceleration of sprinter and time taken by the sprinter to reach the given speed

Data given

Speed of sprinter

Distance travelled

Step 2 of 3:

We can find the acceleration of the acceleration using relation

Here

Initial velocity of sprinter

Substituting values we get

Hence we have the average acceleration of the sprinter as

Step 3 of 3
