Momentum and Vectors

  1. Nov 8, 2004 #1
    Ok, so I've started on momentum recently but now I've hit a problem. I'm not sure how to handle the following situation:

    A 1300 kg car moving at 5.0 m/s is initially traveling north in the positive y direction. After completing a 90° right-hand turn to the positive x direction in 4.4 s, the inattentive operator drives into a tree, which stops the car in 350 ms.
    (a) In unit-vector notation, what is the impulse on the car during the turn?

    (b) In unit-vector notation, what is the impulse on the car during the collision?

    (c) What is the average force that acts on the car during the turn?

    (d) What is the average force that acts on the car during the collision?

    (e) What is the angle between the average force in (c) and the positive x direction?

    Help is appreciated :eek:

    Any part in particular?

    Do you know what impulse is?

    How would you go about calculating average force? Or, for that matter, average anything?
