You are testing a new amusement park roller coaster with an empty car of mass 112 kg. One part of the track is a vertical loop with a radius of 12 m. At the bottom of the loop, the car has a speed of 25 m/s. At the top of the loop, its speed is 7 m/s. As the car rolls from the bottom to the top of the loop, how much work is done by friction. Round the final answer to a whole number.

A box with with a mass m = 2kg is being pushed up a ramp by an unknown pushing force Fp. The coefficient of static friction between the box and interface is 0.7. The coefficient of kinetic friction between the box and interface is 0.6. The incline of the ramp is 15 degrees. The velocity of the box is constant. The surface of the ramp is 12 m. What is the work done by normal force while the box is being pushed the entire length of the ramp? [ I think that it is 0 N, since the x component of normal force which is parallel to motion is 0. Is that correct?]
Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N. How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

Do the following situations result in positive work, negative work, or zero work? Force is perpendicular to displacement. A force slows an object down. Force acts in the same direction as displacement. Force acts in the opposite direction of displacement. A force acts on an object that remains stationary.
A 5.8 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals.

In the arrangement of the first figure, we gradually pull the block from x = 0 to x = +3.0 cm, where it is stationary. The second figure gives the work that our force does on the block. The scale of the figure's vertical axis is set by Ws = 1.0 J. We then pull the block out to x = +6.0 cm and release it from rest. How much work does the spring do on the block when the block moves from xi = +6.0 cm to (a) x = +4.0 cm, (b) x = -1.0 cm, and (c) x = -6.0 cm?
An object slides on an inclined plane that has a slope of 30 degrees. The height of one end of the inclined plane relative to the other end is 2.0 m.
