Two cars collide at an intersection. Car A, with a mass of 2000 kg , is going from west to east, while car B, of mass 1300 kg , is going from north to south at 17.0 m/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 65.0 ∘ south of east from the point of impact.

Part A: How fast were the enmeshed cars moving just after the collision?

v=_____________m/s

Part B: How fast was car AA going just before the collision?

Va=_____________m/s

Solutions

Expert Solution

Here we know that according to the conservation of linear momentum, the momentum of the system befor and after is equal.we have to use the momentum conservation for x and y direction before and after collision.
