We set up a very icy (in fact, frictionless) ramp at just the correct angle so that a puck will slide down the ramp with an acceleration of 4.0 m/s2. I station myself at a point that is 2.0 m (along the ramp) from the bottom. Let’s call this place the origin (x=0), and let downhill al ong the ramp be the positive x direction. From the origin, I now launch a puck up the ramp with a speed of...

A 2 kg block is sliding down a plane inclined at 30˚ to the horizontal. The coefficient of friction between the block and the plane is 0.25. How much work is done by gravity if the block slides 5 m? How much work is done by friction? If the block starts from rest, what is its speed after sliding the 5 m?
