A horisontal force Fp= 375 N acts on a 2.0kg block. The force pushes the block 10.0 m up along a 30 degree fricitonless incline. Find A) work done by force Fp, b) speed of the block after this dipslacement (assume that it's 0 initially), and c) if there is friction, what must the doefficeint be if the the final velocity was only half of the speed found in part b?
