Q. A skier (m=55.0 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 6.90 m and D = 10.4 m, determine H.

Q. A 1140-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Using the data, determine (1) the magnitude of the tension in the wire and the magnitudes of the (2) horizontal and (3) vertical components of the force that the wall exerts on the left end of the beam.
