A 2561-kg van runs into the back of a 823-kg compact car at rest. They move off together at 8.5 m/s. Assuming the friction with the road is negligible, calculate the initial speed of the van.

  • physics -

    final momentum = initial momentum

    (2561+823)(8.5)= 2561 V + 823 (0)

  • Physics -

    Final momentum = Initial Momentum
    (2561+823)(8.5) = 2561V + 823(0)
    (3384)(8.5) = 2561V
    28764 = 2561V
    11.23m/s = V
