q3b

(b) Two balls A and B have a mass of 450 g and mB kg, respectively. If they collide with the
initial velocities shown in Figure Q3(b) and knowing that the coefficient of restitution is
0.7 and friction can be neglected, calculate the magnitude and direction of velocities just
after the impact (Use the x and y reference axes).
