A particle P P\,P is projected with a velocity (3i+2.8j)ms−1(3\mathbf{i} + 2.8\mathbf{j})\text{ms}^{-1}(3i+2.8j)ms−1 from a point 14m above the ground. Take g=9.8 ms−2g=9.8\text{ ms}^{-2}g=9.8 ms−2 and give answers to 2 significant figures where appropriate.
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.
