(a) (i) State one of the Newton’s law of motion.
(ii) A body resting on a horizontal surface is given an initial velocity V so that it slides on the surface for some distance before coming
to a stop.

Table 1 shows the distance d moved by the body of various values of V.
Given that V2 = 20μd where μ is a constant for the surface, plot an appropriate graph and use it to determine μ.
(b) A train of mass 200 tonnes starts from rest and accelerates uniformly at 0.5ms-2.
Determine its momentum after moving 100m.
