A rock is thrown under a bridge at an initial speed of 10 m s − 1 and an angle of 36.9 degrees from the vertical, as shown. At the same time, a boat is passing under the bridge traveling 6 m s − 1 in the direction shown. See the note on the formula sheet about the values of trigonometric functions for this angle. a) Find the vertical and horizontal components of the initial speed of the rock seen by a person on the bridge. Clearly indicate your choice of axes in your drawing. b) Find the vertical and horizontal components of the initial speed of the rock seen by the person in the boat. Clearly indicate your choice of axes in your drawing. c) Draw a clear vector diagram showing how to relate the speed with which the rock appears to be moving when viewed from the bridge, the speed with which the rock appears to be moving as seen by the person on the boat and the speed of the boat with respect to the bridge.

A large wooden turntable in the shape of a flat disk has a radius of 2.30 m and a total mass of 120 kg. The turntable is initially rotating at 3.15 rad/s about a vertical axis through its center. Suddenly, a 71.0 kg parachutist makes a soft landing on the turntable at a point on its outer edge. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Anyone can be a ballerina. Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle.) Express your answer in radians per second. W = ΜΕ ΑΣΦ ? rad/s
