2. 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 1500 kg, is going from north to south at 15 m/s.

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° south of east from the point of impact. a. How fast were the enmeshed cars moving just after the collision? b. How fast was car A going just before the collision?

Question

2. 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 1500 kg, is going from north to south at 15 m/s.

afterward. 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° south of east
from the point of impact.
a. How fast were the enmeshed cars moving just after the collision?
b. How fast was car A going just before the collision?
