1. The problem statement, all variables and given/known data

A heavy block of mass m is slowly placed on a conveyer belt moving with speed v. If coefficient of friction between block and the belt is u (mu), the block will slide on the belt through distance ?

2. Relevant equations

3. The attempt at a solution
i am not able to understand this question, please help me to understand and show me way to get command over this type questions.
Thank you.

hi jatin1990!
the block starts with speed 0

at first, it will slide on the belt, in other words its speed will be less than v

eventually, its speed will equal v, and it will stop sliding

so you need to find the maximum horizontal force on the block, and the maximum acceleration

how far will the block travel on the belt to go from speed 0 to speed v with that acceleration?
