A 40 kg ice skater glides with a speed of 2.0 m/s toward a 10.0 kg sled at rest on the ice. The ice skater reaches the sled and hold to it. The ice skater and the sled then continue sliding in the same direction in which the ice skater was originally skating. What is the speed of the ice skater and the sled after they collide??

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
