In the figure, a block slides down an incline. As it moves from point A to point B, which are 4.1 m apart, force F acts on the block, with magnitude 4.8 N and directed down the incline. The magnitude of the frictional force acting on the block is 13 N. If the kinetic energy of the block increases by 44 J between A and B, how much work is done on the block by the gravitational force as the block moves from A to B? Number i Units

A block of mass 15.0 kg is pulled up from rest on a rough incline. The pulling force F =100.0 N that makes a 5.00° angle with the incline and the incline itself makes an angle of 10.0° with the horizontal. The coefficient of kinetic friction is 0.300, and the block is pulled 3.00 m on the incline. (a) How much work is done by the gravitational force on the block?

A person pulls a crate 48.4 meters along a horizontal floor by a constant force 108.2 N, which acts at 37 degrees. The floor is rough and exerts a friction force 49.8 N. What is the total net work done on the crate?

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?

A crate of mass 8.00 kg is pulled by a force F = 250 N parallel to the incline over a distance d = 4.00 m along the incline. There is also kinetic friction that acts on the mass as it is being pulled along the incline. The coefficient of kinetic friction is mk = 0.597 and the inçline makes an angle of 36.8° with the horizontal. What is the net work done by both the pulling force AND the kinetic friction force on the crate on the mass over the distance? {Consider the definition of work} mg O 952 J O 850 J O 777 J O 570 J O 398 J
