+ Math problems kinetic potential energy?

1. It is said that Galileo dropped objects from the Leaning Tower of Pisa to determine whether light or heavy objects fall faster. If Galileo had dropped to 5.0 kg cannon ball on the ground from a height of 12 meters, which would have been the change in the PE (potential energy) of the cannonball? I just want to check if the correct answer for this. 2.The 2000 Belmont Stakes, commendable, ran the horse race at an average speed of 15.98 m / s. If hockey commendable and Pat Day had a combined mass of 550.0 kg, which was the KE (kinetic energy) to cross the finish line? i know that the formula for this, but I go out with a number Uber long for some reason.

An object of the gravitational potential energy is calculated using MGH, where m is mass, g is the gravitational constant (9.81 for the Earth) and H is the height in meters. Therefore, the change to record. pot. energy is 5 x 9.81 x 12, which is 589J. - The formula for kinetic energy is 0.5 (m) (v ^ 2) - use this service: 0.5 x 550 x 15.98 ^ 2 Or 70.2kJ = 70224J. Hope that helps!
