A 5.0 n block rests on an incline 3 m above the bottom of the incline, as shown. the block is then hit by a hammer so that it has a speed of 1.0 m/s down the incline after being hit. if the incline is 5 m long, and the coefficient of kinetic friction between the block and the incline is μk = 0.75, what is the block's speed when it reaches the bottom of the incline
