A 7.50-kg box slides up a 25.0o ramp with an initial speed of 7.50 m/s. The coefficient of kinetic friction between the box and ramp is 0.333. You wish to calculate the distance the box will move up the ramp before coming to a stop using mechanical-energy (NOT force-motion or the work-kinetic energy.)

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

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

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

A box (with a penguin inside) with mass, M, slides down a frictionless ramp, starting a height H above ground level. At the lowest point of the ramp (height = -0.1H) it slides through a curved section of track with radius, R= 0.25H. The box (w/ penguin) then rises to ground level (height = 0) and at that point, leaves a jump at an angle θ. At the highest point of its trajectory, h2, it strikes a blob of glue...

A 0.990 kg block slides on a frictionless, horizontal surface with a speed of 1.40 m/s. The block encounters an unstretched spring with a force constant of 231 N/m. Before the block comes to rest, the spring is compressed by 9.17 cm. 1) Suppose the force constant of the spring is doubled, but the mass and speed of the block remain the same. By what multiplicative factor do you expect the maximum compression of the spring to change? Explain. 2)...
