The Relationship Between KE and PE – Practice
1) What is the potential energy of a 800gm object at a height of 3.2m?
2) What is the kinetic energy of a 50kg child skiing at 36 km/hr?
3) An object with a mass of 0.04kg was dropped from the top of a 75m high building. Calculate the final velocity of the object using the conservation of energy law:
4) A 150gm golf ball had a final vertical velocity of 16 m/s. From what height did the golf ball fall from?
2) 2500 J
3) 38.3 m/s
4) 13.1 m
