A certain force causes an object to acceleration with an acceleration of 6.85 m/s/s. If the mass is increased by a factor of 2.64 and the force is increased by a factor of 3.85 , what is the new acceleration that the object will experience?

  • Physics Grade 11 -

    F=m*6.85
    F*3.85=2.64*m*a

    solve for a

    a=m*6.85*3.85/(2.64m)

    check my reasoning

    Remember that F = m a ;
    therefore, a = F/m.

    If F' = 3.85 F and m' = 2.64 m
    The new acceleration is:
    a' = F'/m' = (3.84/2.64)*(F/m)

    = 1.455 F/m = 1.455 a

    Complete by inserting the original value of a.
