Question

A Martian rover found an interesting rock that could contain signs of what Mars was like long ago. It grabbed

it with its rover arm and raised it to a height of 0.2 m. Then it dropped it and found that it had a kinetic
energy of 12 J when it struck the ground. Note that Mars has an acceleration due to gravity of 3.77 m/s2.
Complete the following equations to determine the rock's potential energy if it were brought to earth and
dropped from a height of 1 meter. Use what you know about calculating gravitational potential energy to
correctly set up and solve the equation.
PE- m
XH
- PE

Answer 1

It would be PE=16kg * 9.8 m/s^2 * 1m = 160 J
