Calculate the potential energy, kinetic energy, mechanical energy, velocity, and height of the ball at the locations (1), (2), (3), and (4). Show your work below then insert your answers in the blank space provided (PE = , KE = etc.). PE is potential energy, KE is kinetic energy, and ME is mechanical energy.

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
