Starting from rest, a 5 kg block slides 2.5 m down a roughly 30 degree incline. the coefficient of kinetic friction between the block and the incline is uk= .436. Determine a) the work done by the force of gravity, b) the work done by the friction force between the rock and the incline and c) the work done by the normal force. d) qualitatively how would answers change if a shorter ramp at a steeper angle were used to span the same vertical height. Please use neat diagrams + explanations- I'm quite confused. Thank you!!

A block of mass m = 2.30 kg slides down a 30.0∘ incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.20 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored. a) Determine the speed of the block with mass m = 2.30 kg after the collision. b)Determine the speed of...

A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.3-m -wide horizontal surface, then hits a horizontal spring with spring constant 480 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.3-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.26. What is the speed of the box just before hitting the...

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 62.0 kg, and the height of the water slide is 12.4 m. If the kinetic frictional force does -5.72 × 103 J of work, how fast is the student going at the bottom of the slide?
