A 3800 kg open railroad car coasts along with a constant speed of 8.60 m/s on a level track. Snow begins to fall vertically and fills the car at a rate of 3.50 kg/min. ignoring friction with the tracks what is the speed of the car after 90.0 minutes?

  • Physics -

    momentuminitial=momentumfinal

    3800*8.60=(3800+3.50*time)v(t)
    solve for v(t) for t=90min
