Question

How much force is needed to stop an 80kg football player if he decelerates at 5m/s2

Answer 1

This can be solve using newtons second law of motion

F = ma

Where F is the force applied

M is the mass

A is the acceleration

Substituting the given values

F = ma

F = ( 80 kg ) ( 5 m/s2)

F = 400 N of force needed
