Abowler throws a bowling ball of radius r = 11 cm down the lane with initial speed v₀ = 7.5 m/s. the ball is thrown in such a way that it skids for a certain distance before it starts to roll. it is not rotating at all when it first hits the lane, its motion being pure translation. the coefficient of kinetic friction between the ball and the lane is 0.29.
(a) for what length of time does the ball skid? s
(b) how far down the lane does it skid? m
(c) how fast is it moving when it starts to roll? m/s

At the negative terminal of the battery the electron has electric potential energy. what happens to this energy as the electron jumps from the negative to the positive terminal?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
