1. A block of mass m = 0.23 kg slides with initial velocity
v0 = 1.4 m/s along a frictionless surface (as in the
figure). The block next slides through a region of length d = 0.25

the block slides up a curved ramp until momentarily coming to rest
at a height h above the level surface. If the kinetic friction
coefficient μ k = 0.204, what height h does...

A mass m = 14 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.12, for a
distance d = 5.9 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 38° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 38°
(thus on the incline it is...

A block of ice at 0oC whose mass initially is m = 42.1 kg slides along a horizontal surface, starting at a speed v0 = 2.35 m/s and finally coming to rest after traveling a distance d = 2.93 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)
