Physics

A 7.50-kg box slides up a 25.0o ramp with an initial speed of7.50 m/s. The coefficient of kinetic friction between the box andramp is 0.333. You wish to calculate the distance the box will moveup the ramp before coming to a stop using mechanical-energy (NOTforce-motion or the work-kinetic energy.)

a. Write the correct equation for solving the problem, and thenfully justify its use. (Start by identifying the objects in thesystem [only the required objects] and then proceeding as inclass.)

b. Beginning with the equation in (a), calculate the desireddistance.

c. Calculate the change in the thermal energy of the system asthe box moves from the bottom of the ramp to where it stops.
