A ball of mass 3 kg falls from a height of 20 m. Calculate the gravitational potential energy of the ball just before it fell.
Added by Natalie L.
Step 1
We know that the gravitational potential energy (GPE) of an object is given by the formula: GPE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2 on Earth), and h is the height of the object above a reference point. Show more…

If the potential energy of a ball held 20 m above the ground is 30 J, what is the total energy of the ball (PE + KE) after it has been dropped and is 5 m from impact?
