Homework Help: F=bt ?

  1. Sep 7, 2010 #1
    So I have the problem:

    A particle of mass m is at rest at t=0. A linearly increasing force F=bt is applied. Find the velocity and displacement of the particle at t=t1>0

    What exactly is bt?
    Can it be set equal to ma?

    Yes, it can be set equal to ma, or maybe even better bt=m*dv/dt, which if you don't know diff eq (which I'm assuming you don't) will lead to

    [tex]\int \frac{b}{m} t dt = \int dv[/tex]

    Hopefully you know how to integrate :)

    A similar procedure to obtain the integrands for displacement can be used.
