Answer questions 4-5 4) A 0.750-kg peach can is at rest in a shopping cart at the edge of a hill. A strong wind setsit into motion, sending it down a 6.32 meter high hill. The cart hits a tree stump. Thepeach can, being in motion, continue in motion until it finally collides with a car. Uponimpact, the peach can exert an average force of 721 N upon the car body.a. Determine the gravitational potential energy of the peach can when it is at rest atthe top of the hill.hi2b. Determine the kinetic energy of the peach can when it reaches the bottom of thehill. What assumptions did you make?c. Determine the depth of the dent the can makes on the car. What assumptions didyou make? 5) A bouncy ball that makes a perfectly elastic collision in the absence of air resistance (avacuum) could be a candidate for a perpetual motion machine. A physics class collects data(below) on bouncy balls from three companies using a cylinder in which all air was removed. Allbouncy balls were dropped from a height of 1.5 m.CompanyXYZMass of Bouncy Ball(kg)0.050.080.10Velocity immediatelyafter bounce (m/s)5.385.255.31a.Do any of the following companies make a bouncy ball that could result in aperpetual motion machine? Briefly explain your thinking.b.Rank the three companies in increasing order of energy lost to surroundings.Briefly explain your thinking.
