Askater with an initial speed of 7.30 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. air resistance is negligible. (a) the coefficient of kinetic friction between the ice and the skate blades is 0.105. find the deceleration caused by kinetic friction. (b) how far will the skater travel before coming to rest?

Aforce of 34.5 newtons is applied to an object at an angle of 45 º with the horizontal. what is the force acting on the object in the horizontal direction?

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?
