A box of mass m slides with an initial velocity of 3 m/s down a 1.2 meter long ramp which is inclined 20˝ from the horizontal. The coefficient of kinetic friction between the ramp and box is .45.

a) Determine the direction and magnitude of the acceleration of the box as it slides down the incline - is it slowing down or speeding up?

b) How much time does it take for the box to get to the end of the ramp?

A mass M slides downward along a rough plane surface inclined at angle \Theta\: Θ = 25.94 in degrees relative to the horizontal. Initially the mass has a speed V_0\: V 0 = 7.51 m/s, before it slides a distance L = 1.0 m down the incline. During this sliding, the magnitude of the power associated with the work done by friction is equal to the magnitude of the power associated with the work done by the gravitational force. What...
