Question

6. A snowball that will be used to build a snowman is at the top of the only hill in town and weighs 22

Answer 1

Answer:

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

$h=\frac {PE}{W}$

Substituting 520 J for PE and 22 N for W then

$h=\frac {520J}{22}=23.636363636363m\\h\approx$
