A force of 3.0 newtons applied to an object produces a change in velocity of 12 meters per second in 0.40 second. the mass of the object is?
I am not sure how to solve this problem. Formula for momentum is
p= mass times velocity
impulse (J) = Fnet times time in seconds

    Since F = M*a, use

    M = F/a

    The acceleration (a) is (V2-V1)/t
    = 12/0.4 = 30 m/s^2

    M = 3.0/30 = 0.10 kg.

    Oh. That was quite straight forward. Thank you.
