1. Gravitational energy (in joules)
= mgh
where
m=mass (k)
g=acceleration due to gravity (m/s²)
h=height (m)
Solve for h.

2. We use the formula
PE = mgh
where
PE = potential energy (J)
m = mass (kg)
g = acceleration due to gravity = 9.8 m/s^2
h = height (m)

Substituting,
1970 = 82(9.8)(h)
h = 2.45 m

hope this helps~ `u`
