A 50.0g ball of clay traveling east at 3.00 m/s collides and sticks
together with a 50.0g ball of clay traveling north at 3.50m/s.
What is the speed and direction of the resulting ball of clay?

  • Physics -

    initial east momentum = 150
    initial north momentum = 175

    final mass = 100 g

    initial east momentum = final
    so
    final east = 150 = 100 u
    u = 1.5

    initial north momentum = final
    so
    final north = 175 = 100 v
    v = 1.75

    speed = sqrt (1.5^2+1.75^2)

    tan angle n of e = 1.75/1.5
