Question
(a)
A block of mass 13.6 kg is sliding at an initial velocity of 4.65 m/s along horizontal surface
right. The
surface has a coefficient of kinetic friction of 0.254. How far will it slide before coming to rest? Calculate the
time it takes to come to rest?
(b) A motorcycle and a truck are both moving in the same
direction in adjacent lanes on a highway. Mass of the
truck is 8 times that of the motorcycle. At a particular
truck
instant, the speed of the motorcycle is four times as
motorcycle
4v
large as the speed of the truck v. Calculate the ratio of
kinetic energies of the motorcycle and truck. Calculate
the ratio of momentum of the two bodies.
