the figure shows a ball with mass m= 0.453kg attatched to the end of a thin rod with length L=0.342m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown then given enough of a downward push to cause the ball to swing down and around and just reach the vertically upward position, with zero speed there. How much work is done on the ball by the gravitational force from the initial point to (a) the lowest point, (b) the highest point, and (c) the point on the right level with the initial point? If the gravitational potential energy of the ball-Earth system is taken to be zero at the initial point, what is it when the ball reaches (d) the lowest point, (e) the highest point, and (f) the point on the right level with the initial point?

Final answer:The work done on the ball by the gravitational force and the gravitational potential energy at different points on the circular motion.Explanation:The work done on the ball by thegravitational forcedepends on the position of the ball in its vertical circle. Let's consider each position:At the lowest point, the work done by the gravitational force is equal to the change in gravitational potential energy. This is given by the equation Work = mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height of the lowest point.At the highest point, the work done by the gravitational force is again equal to the change in gravitational potential energy. This is equal to zero because the gravitational potential energy is zero at this point.At the point on the right level with the initial point, the work done by the gravitational force is also equal to the change in gravitational potential energy. This is again zero because the gravitational potential energy is zero at this point.If the gravitational potential energy of the ball-Earth system is taken to be zero at the initial point, then the gravitational potential energy at each of the mentioned points is as follows:The lowest point: 0 JThe highest point: 0 JThe point on the right level with the initial point: 0 JLearn more about work, gravitational potential energy here:brainly.com/question/35704730#SPJ11...
