How far to the nearest tenth of a meter can a runner running at 11 m/s run in the time it takes a rock to fall from rest 90 meters?

3 answers

Calculate the time t it takes a rock to fall 90 m.

90 = (1/2) g t^2

Multiply that time by 11 m/s.

These questions are not hard. You need to show some work of your own.
obviously some people find these hard or they wouldn't be asking them.
