Ok, thank you very much.

Okay, I've done it thank you very much. Just wondering which root I have to choose (actually I know which one because I have the result but I probably wouldn't if I didn't have). Can you please shortly explain why it has to be the second one in this case.

Yes, but I don't know how to apply this for that problem.

But I still don't know how can I determine that time from my task.

So acceleration has to be negative and grow. But I still have no clue how to get that time from it. Am I right with that?

Hello, no, I have tried to solve the integral for velocity, but I wasn't successful. So when I know that F=ma and therefore a=F/m, I can solve the acceleration, but I'm not sure what should be the next. Thank you.

Hello, I have the force defined as a function of time, where F=A-Bt and A=100N, B=100Ns-1. I have to determine, how long it will take for object to stop, if t0=0s and v0=0,2ms-1 and mass of the object is m=10kg. Can somebody please help me with this, because I'm having hard time with this task.
