Please give the answer and EXPLAIN for problems 1 and 2.
At the fair, a little girl and her father ride the bumper cars. The girl's car moving to the east, collides with the father's car, which is initially at rest. After the collision, the girl's car is moving west and the father's car east. 1. The direction of the change in velocity vector of the girl's car from before to after the collision is: a) to the east b) to the west c) zero d) not enough information 2. The direction of the change in velocity vector of the father's car is a) to the east b) to the west c) zerod) not enough informationExplanation / Answer
1) girls direction of change in velocity = final velocity --initial velocity
= Towards west-towards east
= Towards west -(--towards west)
= 2 towards west ------- that is towards west
2) father's direction of change in velocity = final --initial
= East --- direction
= Towards east
