Hello! Can someone please help me with all these problems? Thanks!An object weighing 50kg is pushed off a 80m building.What is the potential energy and the kinetic energy of the object at rest at the height of 80m?Potential – 40000Kinetic – What is the potential energy and kinetic energy of the object at a height of 10m if the object is traveling downward at 40m/s.An object weighs 150N. If the object is carried up a flight of stairs measuring 5m, how much work is required?If a machine is able to lift a pallet of books weighing 1,500N 15m in 5 seconds, and another machine is able to life the same pallet of books 15 m in 7.5 seconds. Which machine does more work? Explain your answer (show your math to support your answer)Which machine is more powerful? By how much? (Show your math to support your answer)If a space ship weighing 5,000kg is traveling in orbit around the Earth at a speed of 11m/s needs to increase its speed to meet up with its resupply rocket 700m away orbiting at the same speed then:What is the Force required to reach the resupply capsuleWhat is the Kinetic Energy of the ship before it changes speed?What is the Kinetic Energy of the ship after it changes speed? (Hint w=ΔKE) Show your work.Assume both of the screws below are the same length.What screw will require more force to screw into a board? Explain your answer.If both screws are fastened in the same amount of time, which screw will require more power? Explain your answer.
