Answer to Question #294454 in Physics for LUNA

Question #294454

A 5-kg box is dropped from a height of 68 m. What is the potential energy of the ball? Assuming that the reference position is the ground.

Expert's answer

Given:

"m=\\rm 5\\: kg"

"h=68\\:\\rm m"

The potential energy of the ball is given by

"E_p=mgh\\\\\n=\\rm 5\\:kg*9.8\\: N\/kg*68\\: m=3332\\: J"
