Which of the following statements correctly describes the
relationship between an object's gravitational potential energy and
its height above the ground?
proportional to the square of the object's height above the
ground
directly proportional to the object's height above the
ground
inversely proportional to the object's height above the
ground
proportional to the square root of the object's height above the
ground
An archer is able to shoot an arrow with a mass of 0.050 kg at a
speed of 120 km/h. If a baseball of mass 0.15 kg is given the same
kinetic energy, determine its speed.
A 50 kg student bounces up from a trampoline with a speed of 3.4
m/s. Determine the work done on the student by the force of gravity
when she is 5.3 m above the trampoline.
