Question

10. Two identical balls are simultaneously thrown towardseach other from points P and Q horizontally separatedby 8 m, and situated at heights 4 m and 8 m above theground. One ball is thrown from P horizontally with aspeed of 8 mswhile the other is thrown downwardwith an initial speed of v at an angle of 45^° to thehorizontal (figure). The two balls collide in space,calculate (a) the initial speed of ball thrown from thepoint Q, (b) coordinates of the point of collision.g= 10 ms2.Q
