6. A snowball that will be used to build a snowman is at the top of the only hill in town and weighs 22 N. If the Potential Energy of the snowball is 520 J, what is the height of the snowy hill?

copied from opudodennis

23.64 m

Explanation:

Potential energy is given by

PE=mgh

Where m us the mass of snowball, g is acceleration due to gravity, h is height.

Also, the weight of an object is given by W=mg hence replacing mg in the above equation with W we obtain

PE=Wh

Making h the subject of the formula then

h= PE/W

Substituting 520 J for PE and 22 N for W then

h= 520J/22 = 23.636363636363m
