What is the force of an 18kg object accelerating at 4m/a squared?
3. (a) How much work is done in raising a 50.0 kg crate a distance of 3.5 m above a storeroom floor? (b) What is the change of potential energy as a result of this move? (c) How much kinetic energy will the crate have as it falls and hits the floor?
