Determine the mechanical energy for a 5.0 kg stone perched near the edge of a cliff 25.0 m high. Use the base of the cliff as the reference level.

Compare the kinetic energies for a biker and bike (with a combined mass of 80.0 kg) traveling at 3.00 m/s and the same biker and bike traveling twice as fast.

Which has the greater gravitational potential energy - a flower pot-Earth system with a 550 g flower pot sitting on a 1.2 m high shelf or a flower pot-Earth system with a 350 g flower pot sitting on a 1.8 m high shelf?

During a contest that involved throwing a 7.0 kg bowling ball straight up in the air, one contestant exerted a force of 810 N on the ball. If the force was exerted through a distance of 2.0 m, how high did the ball go from the point of release?

A 50.0 kg girl jumps onto a stationary 2.4 kg skateboard at 4.1 m/s. Determine the fraction of the original kinetic energy that was transformed to other forms due to the inelastic nature of the collision.
