1. The moon's orbital speed around Earth is 3.680 x 109 km/h. Suppose the moon suffers a perfectly elastic collision with a comet whose mass is 50.0 percent that of the moon. (A partially inelastic collision would be a much Problem G DATE CLASS more realistic event.) After the collision, the moon moves with a speed of -4.40 x 102 km/h, while the comet moves away from the moon at 5.740 x 109 km/h. What is the comet's speed before...

Problem 2 A 1.0 kg cannonball is fired horizontally with a speed of 200 rn/s at two blocks (each with mass 10.0 kg at rest on a frictionless surface). The ball embeds itself in the first block, and then the ball and block 1 traveling together collide elastically with block 2. All external forces are negligible compared with the net explosion or collision forces. Use the reference frame provided. Neglect the material removed from the block during collision with the...
