An unsupervised child has snuck away from a guided tour on a family vacation to
Mars. They decide it would be fun to throw something from a small cliff, since it will
travel pretty far, given that the acceleration due to gravity on Mars is only 3.7 m/s2.
So, they throw a stone with a speed of 8.2 m/s, at an angle of 60 degrees above the
horizontal. The cliff has a height of 12 meters, and the child releases the thrown stone
at a height of 1.1 meters above the top of the cliff.

How much time passes between when the stone is thrown and when it hits the ground?

What is the horizontal displacement of the stone (between where it thrown and where
it hits the ground)?

What is the speed of the stone when it hits the ground?
