K.C.S.E Physics Q & A - MODEL 2001PP2QN06

​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 I shows the distances d moved by the body of various values of u

Given that v2 is 20 (miu)d where u is a constant for the surface, plot a appropriate graph and use it to determine u.
 Determine values of u on table.
b) A train of mass 200 tonnes starts from rest and accelerates uniformly at 0.5ms-2 determine its momentum after moving 100m.
