Q1. A man pushes on a piano with mass 200 {rm kg} so that it slides at constant velocity down a ramp that is inclined at 18.3^circ above the horizontal floor. Ignore any friction acting on the piano.

Q2. The deepest point in the ocean is in the Mariana Trench, about 11 km deep. The pressure at the ocean floor is huge, about 1.13 x 10^8 N/m2. Compute the change in volume of 1.00 m^3 of water carried from the surface to bottom of the pacific.
