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
