A block, m = 8.0-kg, is released from rest, with v1 = 0.00 m/s,
on a rough incline with θ = 40.0°, as shown in the figure. The
block moves a distance of x = 1.60 m down the incline and acquires
a velocity of v2 = 4.00 m/s.
a) Use Work Energy Theorem to derive an algorithm for the
coefficient of friction in terms of m, v1, v2, θ, x and g. The
problem may not require all of these variables, but do not use or
create other variables.

A block of mass m is pushed against an ideal spring of constant of k, compressing it over a distance x with respect to its natural length. When the block is released, it moves up a rough ramp of inclination θ and coefficient of friction μk.What is the maximum distance (d) that the block travels up the incline? You MUST use conservation of energy to solve this problem. Epress your answers in term of m, g, k, μk and θ.

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...
