KE = PE = mgh = 100*10*200 = 200,000J
A body of mass 100kg is placed at a point 2m above the ground. What is the potential energy with reference to the ground (g=10m/s)

A body of mass 100kg is placed at a point 2m above the ground. What is the potential energy with reference to the ground? (g=10m/s)
PE=MGH
mass=100kg,gravity=10m/s,height=2m.
100*10*2=2000joules
mass=100kg,gravity=10m/s,height=2m.
100*10*2=2000joules
with what energy does the body strike the grounds level?
