A machine is designed to push packages into a storage container for overseas shipping. On a certain package, the machine applies a pushing force at an angle of 35 above horizontal. The ramp that the package slides up is 22° above horizontal. If the ramp is 4.11 m long, and the machine performs 1150 J of work, how much force does the machine apply to the package? 342 N O 302 N O 287 N 280 N

Rawly has a mass of 79.0 kg, and he is sledding down a hill that is 29.5 m tall. As he goes down the hill, his gravitational potential energy is converted into kinetic energy. When he has descended 21.0m down the hill, how much kinetic and gravitational potential energy does he have? O GPE = 22, 900 J; K E = 6590 J O GPE = 6590 J: KE = 16, 300 J O GPE 16, 300 J: KE = 6590 J O GPE = 0 KE 22, 900 J Harriet is practicing archery. As she draws back an arrow, the arrow has 34.3 J of elastic potnetial energy, and 0.40 J of gravitational potential energy. How much kinetic energy will the arrow have when it is about to hit the ground? O 33.9 J O 34.7 J O 0.4 J O 34.3 J
