Question

4A. How high is a 12 kg monkey in a tree if it has 509 J of gravitational potential Energy?

B. Assuming no energy loss due to friction, what are his GPE, KE and velocity at a point 2.0 meters above ground as it falls.

Answer 1

4A. PE = MxGxH. (You can consider g as 9.8 / 10m/s as well)

509 J = 12x10xH

509 J = 120xH

H = 509/120

H = 4.24 m

Hope u got the answer....pls rate the answer if it is helpful for u....and I'm sorry I could not understand B part so I didn't do it.

Thank you
