Question

An object with a mass of 100 grams is dropped from a certain height and has a velocity of 60 meters/second. if the potential energy of this object is 179.99 joules, how high was the object when it was dropped?

Answer 1

KE=PE
1/2*m*V^2=mgh
1/2*0.100*(60)^2=0.100*10*h
0.05*3600=h
180 meters=h
