a block of mass m is sliding with an initial speed vi along a horizontal surface with negligible friction. a constant force of magnitude fa is exerted on the object at an upward angle of 60∘ from the horizontal, causing the object to speed up. if the block remains in contact with the floor, what is the change in the block’s kinetic energy as it moves a horizontal distance δx ?
