. Two small spheres with masses m1 = 200 g and m2 = 600 g are suspended on two vertical strings of length L = 0.8 m. Sphere m1 is pulled upwards to the left, so that the string makes an angle of 90 with the vertical (dashed line and unlabeled sphere). Sphere m1 is released from rest and collides elastically with sphere m2. Determine the velocity of sphere m1 before the collision. Determine the velocity of sphere m1 after the collision. Determine the velocity of sphere m2 after the collision. Determine the vertical displacement of sphere m1 after the collision. Determine the vertical displacement of sphere m2 after the collision. 9:992:91
