Question

A softball player does a windmill pitch, moving her whole arm in a vertical circle and releasing the ball at the lowest point on the circle.
Keeping in mind that the ball is moving in a circle. If the only forces acting on the ball at the BOTTOM of the circle just BEFORE the ball is released, are N, the normal force straight up by the person's hand and W, the weight force straight down by the earth, how do the magnitudes of the two forces compare?
A. Magnitude of normal force by hand on the ball is greater than magnitude of weight force by earth on the ball
B. Magnitude of normal force by hand on the ball is less than magnitude of weight force by earth on the ball
C. Magnitude of normal force by hand on the ball is equal than magnitude of weight force by earth on the ball A softball player does a windmill pitch, moving her whole arm in a vertical circle and releasing the ball at the lowest point on the circle.
