Astudent wearing frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 45 n. how far must the student be pushed, starting from rest, so that her final kinetic energy is 352 j?

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.

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?

In an experiment, how can i change human errors? be specific.
