A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...

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...

The figure(Figure 1) shows a 1.75-kg block at rest on a ramp of
height h. When the block is released, it slides without friction to

coefficient of kinetic friction 0.650. Part A Find h such that the
block's speed after crossing the rough patch is 3.40 m/s .
