Question

A box of mass m is pushed horizontally on a rough floor with an initial speed of 2 m/s. The coefficient of kinetic friction between the surface and the box is µ_k = 0.1. Calculate the distance the box will move before stopping.

Answer 1

here deccelaration is 0.1×10=1ms^-1

distance travelled= 0^2-2^2/2×-1

= 2m
