Question

A crate pushed along the floor with velocity \vec{v} _{i} slides a distance d after the pushing force is removed.If the mass of the crate is doubled but the initial velocity is not changed, what distance does the crate slide before stopping?

Answers

The friction force F will double if the mass doubles. The deceleration rate, a = F/M = mu*M*g/M, , remains the same. Sliding distance won't change
Very Thanks
