Describe the motion of a ball being thrown straight up in the air in terms of kinetic and potential energy. as the ball rises up and balls back down, how is kinetic and potential energy affected? when is each type of energy the greatest and the least? what is true about the total mechanical energy of the ball?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
