A 0.8 kg block of wood is sliding across a floor at 2 m/s when a half-gram nail from a nail gun travelling 67 m/s horizontally at an angle 35° relative to the direction of the block embeds itself into the wood. (So, the 35° angle is with respect to the x-axis, with x and y both being in the horizontal plane.) (a) What would be the velocity of the block/nail system just after impact? Find also the magnitude and direction of the velocity. Assume that the impact is so fast that friction between the block and the floor can be ignored. (b) How much energy was lost during this collision?
