A particle P projected from a point O on horizontal ground hits the ground after 2.4 seconds. The horizontal component of the initial velocity Of P is ms¯l. (a) Find, in termsofd, the horizontal distance ofPfrom O when it hits the ground. (b) Find the vertical commM1ent of the initial velocity of P. P just clears a vertical wall which is situated at a horizontal distance dm from O. (c) Find the height of the wall. The speed of pas it passes over the wall is 16m (d) Find the value Of d correct to 3 significant figures, o_2kg
