A 3600 kg open railroad car coasts along with a constant speed of 11.0 m/s on a level track. Snow begins to fall vertically and fills the car at a rate of 3.70 kg/min.

Ignoring friction with the tracks, what is the speed of the car after 80.0 min?

  • Physics -

    conservation of momentum
    Momentum before= momentum after.
    3600*11=masssnow*0= (3600+masssnow)Vf

    masssnow= 3.7*80 kg
    solve for Vf.
