?A ball is thrown such th- at the time of flight is sseconds. And the horizontal Resultant is 200m. Find the magnitude and direction of velocity of projection? ans : tf = 5 seconds R = 200m T= zusino 5 = g R usinzo 200m g If using = 5x10 = 25 2 R= 200 = 410000 = acose = 200 = 40 5 u- V 25 + 40 = 2225 tano = using = 25 5 = wrose 40 8 O= tan' (5/8)
