A body P (shown in red) of mass m is at the base of a fixed rough inclined plane of inclination a to the horizontal and elevation h. A light inelastic string is attached to P and passes over a smooth pulley (shown in yellow) at the top of the plane where it is attached to a body Q (shown in white) of mass M initially adjacent to the pulley and able to move vertically downwards. Initially, the system is...

3) A heavy penguin (of mass 12 kg) and a light penguin (of mass 6 kg) are sitting peacefully on a snowy slope. The slope tilts above level ground at an angle of 10 degrees. The heavier penguin is higher up on the slope than the light one and launches itself down the slope, moving at a constant speed of 3 m/s. How fast will the two penguins be moving after the heavy one collides with the lighter one?...
