A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Using the formula

GPE = m*g*h (mass (kg) * gravitational field strength (N/kg) * height (m) )

We can say that -

100 J = 0.5 * 9.8 *  x

x = 100/(0.5 * 9.8)

x = 20.4 m

Your answer is 20.4 m

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
