A 2.0-kg block slides down a frictionless incline from point A to point B. A force (magnitude P = 3.0 N) acts on the block between A and B, as shown. Points A and B are 2.0 m apart. If the kinetic energy of the block at A is 10 J, what is the kinetic energy of the block at B? ( Hint: You are looking for the change in KE. It does not matter if the initial speed at point A is zero or something else. Use conservation of energy and check if there is/are any non conservative force present) 30° 17 J 37 J 24 J 27 J 20 J

A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 81 kg, and the height of the water slide is 11.8 m. If the kinetic frictional force does -5.1 × 103 J of work, how fast is the student going at the bottom of the slide?
A block of mass m = 1.2 kg is placed on a rough incline surface making an angle 0 = 28.5 with horizontal. A force F parallel to the ground is applied to the block.

You pick up a barbell with weights (total mass: 100.0 kg) from the ground to approximately 0.800 m above the ground (roughly equivalent to doing a deadlift). Once it has been lifted, you then carry it 10.0 m at a steady speed before stopping and finally gently lowering the barbell back to the ground. How much work have you done on this barbell in J?

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.
