A 100 lb crate is being pushed across a wooden floor with a force of 40 lb. If mu=0.3, find the acceleration of the crate.

  • Physics -

    a = Fnet/m
    Mass m must be in slugs
    m = 100/32.2 = 3.106 slugs
    Fnet = 40 - 0.3*100 = 10 lb

    Solve for a. It will have units of ft/s^2.
    Divide that by 32.2 ft/s^2 if you want acceleration in g's.

    thank you!
