Constants
A child whirls a ball in a vertical circle.
Part A
Assuming the speed of the ball is constant (an approximation) , when
would the tension in the cord connected to the ball be greatest?
O At the bottom of the circle.
A little after the bottom of the circle when the ball is climbing.
O Nowhere; the cord is stretched the same amount at all points.
At the top of the circle.
A little before the bottom of the circle when the ball is
descending quickly.
