A 16.0 kg canoe moving to the left at 12.0 m/s makes an elastic head-on collision with a 4.00 kg raft moving to the right at 6.00 m/s. After the collision, the raft moves to the left at 22.7 m/s. Disregard any effects of the
water. Find the velocity of the canoe after the collision.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
