At time $t=0$ a person is sliding due east on a flat, frictionless plane of ice. The net force on this person is due to a battery-powered fan the person holds that exerts a southward thrust force on the person. Assuming that drag is negligible, the eastward component of the person's velocity is unaffected by this force.

Question

Quizplus · Accepted Answer

The southward thrust force from the fan is perpendicular to the eastward component of the person's velocity, so it does not affect the magnitude of the eastward velocity, only the direction of the overall velocity vector.
