Asked Oct 1, 2019

Imagine that a sprinter accelerates from rest to a maximum speed of 10.3 m/s in 1.8 s.

In what time interval will he finish the 100-m race if he keeps his speed constant at 10.3 m/s for the last part of the race?

What assumptions did you make?

Step 1

The acceleration of the object is,

Step 2

The travelled distance by the object is,

Step 3

Therefore, the required ...
