You move sphere B along the line until its center-to-center separation from C is d = 4.0 cm. (a) How much work is done on sphere B by you? J (b) How much work is done by the net gravitational force on B due to spheres A and C? J

The figure shows a ball with mass m = 0.354 kg attached to the end of a thin rod with length L = 0.597 m 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 and 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? (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number Units (f) Number Units

A crate of mass 9.2 kg is pulled up a rough incline with an initial speed of 1.46 m/s. The pulling force is 98 N parallel to the incline, which makes an angle of 20.5∘ with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.98 m. (a) How much work is done by the gravitational force on the crate? J (b) Determine the increase in internal energy of the crate-incline system owing to friction. J (c) How much work is done by the 98−N force on the crate? J (d) What is the change in kinetic energy of the crate? J (e) What is the speed of the crate after being pulled 4.98 m? m/s
