A monkey carries a coconut of mass 2 kg to a height of 10 m above ground and later releases the coconut with zero initial velocity to the ground. Calculate a) Potential energy of the coconut before release? b) Kinetic energy of coconut just before it reaches the ground [use conservation of energy].

Step 1
81 m/s²), and $h$ is the height above the ground (10 m). $PE = (2\,\text{kg})(9.81\,\text{m/s}^2)(10\,\text{m})$ $PE = 196.2\,\text{J}$ So, the potential energy of the coconut before release is $\boxed{196.2\,\text{J}}$. Show more…

A 50 kg gorilla is sitting on the limb of a tree 3 meters above the ground. a) Find the potential energy of the gorilla sitting in the tree. b) The gorilla jumps down from the tree limb to the ground. Use the conservation of energy to find the velocity of the gorilla just before hitting the ground. c) Use the conservation of energy to explain why the total energy of the gorilla is 1470 J at 1 m above the ground. d) The gorilla, feeling exuberant, throws a 0.50 kg banana straight up in the air from the ground with an initial energy of 30 J. How high will the banana travel up?
