    @44 l 67% 12:39 Problem Two. An object of mass m starts from rest and slides a distance d down an incline of angle 6. While sliding, it contacts an uncompressed spring as shown in the figure. The object slides an additional distance x as it is brought momentarily to rest by the compression of the spring (with spring constant k). As the spring is being compressed, it scrapes on the ramp causing friction with a with a varying coefficient...

    A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30.0 ◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress...

    As shown below (not to scale), a block of mass starts from rest and slides down a frictionless ramp of height h. Upon reaching the bottom of the ramp, it continues to slide across a flat frictionless surface. It then crosses a "rough patch" on the surface of length d=10m. This rough patch has a coefficient of kinetic friction uK=.1. After crossing the rough patch, the block's final speed is vf=2m/s. What is the height of the ramp? Hint: I...
