A m= 5.0 kg block slides on a flat, smooth track with an
initial speed of vi= 6 m/s. The block slides down a rough incline
that has a vertical height of h = 4 m onto another flat, smooth
track. The block’s final speed is vf= 10 m/s. How much energy is
lost to friction on the block as it slid down the incline?

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
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...
