Question

The world record for pole vaulting is 6.15 m. If the pole vaulter’s gravitational potential is 4942 J, what is his mass?

Answer 1

From the calculations, the mass of the pole is 82 Kg.

What is potential energy?

The term potential energy has to do with the energy that is possessed  by a body by virtue of its position.

Given that;

height = 6.15 m

PE = 4942 J

mass = ??

g = 9.8 m/s^2

Now

PE = mgh

m = PE/gh

m =  4942 J/9.8 m/s^2 * 6.15 m

m = 82 Kg
