A water balloon is thrown straight down with an initial speed of 13.5 m/s from a second floor window, 5.00 m above ground level. With what speed v does the balloon strike the ground? Assume the effects of air resistance are negligible. V= m/s
An external force moves a 2.50-kg box at a constant speed v up a frictionless ramp, as shown in the figure. The force acts in a direction parallel to the ramp. Calculate the work W done on the box by this force as it is pushed up the 5.00-m ramp to a height h = 2.00 m. W = How does the work done on the box compare to the grav change in gravitational potential energy AU, that the box undergoes as it rises to its final height?
