Post the question.
LekhB:
A particle,P,of mass 0.3kg,is moving in a straight line on a rough horizontal floor.The speed of P decreases from 7.5m s-1 to 4 m s-1 in time T seconds.Given that the coefficient of friction between P and the floor is 1/7(one divided by 7) find:
(a) the magnitude of the frictional force opposing the motion of P.
(b) The value of T.
