- Homework Statement
- I am writing the statement of problem here but its figure is in Attempt at a solution.

A 1kg block moving on horizontal rough surface of friction coefficient 0.6 is pushed with a force varying with time t in seconds as shown in figure.If initial velocity of block was 4.5 m/s.Find the velocity (in m/s) at t= 3 s.

- Relevant Equations
- F=Ma

dv/dt=a

Figure given in question-:

I first found out the time when force will be equal ro friction.After force becomes equal to friction there will be no acceleartion further,so velocity after that time will be same.I calculated the velocity by getting a relation of it with time.I got the velocity as 6m/s.But the answer given is 0 m/s.I can't get it.Please help.
