A ball is thrown from the top of a tower 15m high with an initial velocity of (5i+12j)ms−1(5\mathbf{i} + 12\mathbf{j})\text{ms}^{-1}(5i+12j)ms−1.
Find the speed of the ball after 1.5 seconds.
Find the greatest height of the ball above the ground.
Find the horizontal distance travelled by the ball before it hits the ground.
