Question

A 60-kg teenager is standing on a skateboard. What force does the skateboard exert on the

teenager?

Answer 1

Force = mass x acceleration.

In this case , the acceleration is the one due to gravity, g. (Which is 9.81 m/s)

So

Force = mass x acceleration/force due to gravity (or F = mg)

= 60 x 9.81

= 588.6 Newtons
