A particle P P\,P is projected with a velocity (3.2i+7j)ms−1(3.2\mathbf{i} + 7\mathbf{j})\text{ms}^{-1}(3.2i+7j)ms−1 from a point h mh\text{ m}h m above the ground. The greatest height of P P\,P is 8.1 m.
Find the speed of the particle after 2 seconds.
Find the height of the point from which P P\,P is projected.
Find the horizontal distance travelled by P P\,P before it hits the ground.
