Question

A 2.0 kg rock is thrown horizontally from the top of a 100-meter-high cliff on Planet Unicorn with a speed
of 15 m/s. The mass of Planet Unicorn is 1x1025 kg and the top of the cliff is approximately 4000 km
from the center of the planet.
a) What is the value of the acceleration due to gravity on Unicorn in m/s2 ?

b) How far from the base of the cliff does the rock land?

A force of 40.0 N is required to pull the same rock at a constant velocity across a smooth glass
surface on Earth. What force would be required to perform the same experiment on Planet
Unicorn?
