Kinetic versus potential ramp  |  ProblemNeglecting friction, what factor affects the final speed of an object sliding down a ramp? Group of answer choicesThe length of the rampThe height of the rampThe mass of the objectThe path the object takes

A 2.45 kg box, starting from rest, slides down a 6.70 m long ramp inclined at 27.5o from the horizontal. Halfway down the ramp, it hits a second box, with a mass of 1.40 kg. The two boxes stick together and slide the rest of the way down the ramp. The coefficient of kinetic friction between the ramp and the boxes is 0.150. How fast are they going when they reach the bottom?

A lower ramp will be longer, allowing for less force to be used, but makes an object travel a greater distance.

Context: m The object of mass m = 3 kg is at the bottom of the incline, which is at the angle e = 55° with respect to horizontal. The object has initial speed of vo = 5 m/s and begins slide up the incline. There is a friction between the object and the incline. The coefficient of kinetic friction is uk = 0.25. The object moves up the incline and eventually stops under the influence of friction and its own weight. Find: (a) how high up the incline (in m, relative to its original position) the object slides before stopping (careful here - your answer is the height, i.e. the vertical distance between object's final position and the ground); (b) work in J) done by the kinetic friction when the object moves up the incline (careful with the sign); (c) work in J) done by the normal force when the object moves up the incline; (d) work in J) done by the gravity when the object moves up the incline (careful with the sign); (e) when the object reaches the highest point on the incline it begins to slide back down, find object's speed (in m/s) at the bottom of the incline. Answer question

A box moves down a ramp with no friction. At the bottom of the ramp, the box has lost 15.6 joules of potential energy. How much kinetic energy did the box gain as it moved down the ramp?

A box of orange marmalade (14 kg) is slid up a 20° slope with the coefficient of kineticfriction being 0.15 and the coefficient of static friction being 0.25. What is the acceleration ofthe marmalade up the ramp? What is the acceleration down the ramp
