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.
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
