Two cars, the first of mass 1,800 kg was headed east at 26m/s, the second of mass 1,500 was headed north when they collided. Their tangled wreck moved 45 north of east right after the collision. What was the velocity of the second car right before the collision? (Neglect friction forces). Hint: you may want to use the following procedure: Choose a coordinate system such that the origin is at the point of collision, the x- axis points east and the y-axis points north. (a) What was the total x-component of the momentum before the collision? (b) What was the total x-component of the momentum right after the collision? (c) What was the magnitude of the momentum of the wreck right after the collision? (d) What was the magnitude of the y-component of the momentum of the wreck right after the collision? (e) What was the magnitude of the total y-component of the momentum right before the collision? (f) What was the velocity of the second car right before the collision?
