Two identical smooth balls are projected from points O and A on the horizontal ground with same speed of projection The angle of projection in each case is 30 see figure The distance between O and A is 100 m The balls collide in mid air and return to their respective points of projection If the coefficient of restitution is 0 7 find the speed of projection of either ball in m s correct to nearest integer Take g 10 ms 2 and 3 1 7 0 30 30 A
