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.
