A 30g dart is shot straight up at 10m/s . At the same instant, a 24g ball of cork is dropped from 2.0m above the dart.
Part A What is the speed of the cork ball immediately after it is hit by the dart? Assume the collision is exactly head-on and the dart sticks in the cork.
Part B What is the direction of the cork ball immediately after it is hit by the dart?
