Question

An athlete whose weight is 800N runs a race with acceleration of 5 metres per second square. What is the force that the athlete ran with?

Answer 1

`F = 400 N`

Explanation:

Using `g = 10 m/s^2, " "m = "weight"/g = (800 N)/(10 m/s^2) = 80 kg.`

So then `F = m*a = 80 kg*5 m/s^2 = 400 N`

I hope this helps,
