Kuok Ching Ching participates in the water diving event in the Olympics. She jumps from the springboard with velocity of 20 ms-' at 30* above horizontal, on a spring board that is 3m ab the water level, as shown in the diagram below: 20 ms- 30' 3m Water level (a) Calculate the magnitude of the vertical component and horizontal component of initial velocity. [2] (b) Calculate the maximum height above the water level. [3] (c) With the aid of a vector diagram, calculate the magnitude and direction of final velocity at t = 2s. [5]
