i) The trajectory of a ball after it has been thrown with an initial speed of 10.0 m/s from point P is shown. The ball reaches its maximum height at point Q; 4.00 m higher than its starting height. Determine: - a) the value of the angle, e, that the initial velocity vector makes with the horizontal , b) the speed of the ball at point Q. Neglect air resistance 4,00 m V=10,0 m s-1 R ii) A car travels along the road with a speed v as a function of sin metres. 2) = (2s) m/s 50 m n Determine the magnitude of the total acceleration at s = 15 m. REMEMBER: use vdv = ads where dv will be d.2s.
