A rock of mass 13 kg is tied to a string of length 2.5 m, with the other end of the string fastened to the ceiling of a tall room. While hanging vertically, the rock is given an initial horizontal velocity of 2.1 m/s. How high will the rock swing? Express your answer in terms of the angle θ that the string makes with the vertical when the rock is at its highest point.
