icture the situation where a ball is attached to the end ofa string. By whirling the ball with the string, you can make it move around in a horizontal circle at constantspeed.(a) What is the netverticalforce on the ball? Sketch a free-body diagram of the forces acting on the ballfor some point in its circular orbit.(b) What must be the direction of the ball’s acceleration to keep it moving in a horizontal circle?(c) From your free-body diagram in part (a), determine the net force acting on the ball. Does this agreewith part (b)?
