Question

50 points please help

Answer 1

Given

Mass m = 70 kg

Acceleration a = 5 m/s²

To determine

Force F = ?

Using the formula

F = ma

substituting m = 70 kg and a = 5 m/s²

F = 70 × 5

F = 350 N

Therefore, the sprinter is exterting a 350 N force.

Question No 7

Given

Mass m = 80 kg

Acceleration a = 10 m/s²

To determine

Force F = ?

Using the formula

F = ma

substituting m = 80 kg and a = 10 m/s²

F = 80 × 10

F = 800 N

Therefore, the sprinter is exterting a 800 N force.
