A particle P P\,P is projected with a velocity (4i+4j)ms−1(4\mathbf{i} + 4\mathbf{j})\text{ms}^{-1}(4i+4j)ms−1 from a point 20m above the ground. Take the acceleration due to gravity to be 9.8ms-2. Give your answers to 2 significant figures in parts (a) and (c).
Find the speed of the particle after 2 seconds.
Find the greatest height of PPP.
Find the horizontal distance travelled by P P\,P before it hits the ground.
