Ball A is moving upward along the y axis at Va = 2.5 m/s and ball B is moving to the right along the x axis with speed Vb= 3.9 m/s. After the collision, assumed elastic, ball B is moving along the positive y axis ( Figure 1). What is the final direction of ball A? Express your answer using two significant figures.

The velocity of the car right after the collision is 18.0 m/s to the east. Two images depicting a before and after scenario of a car colliding with the back of a truck. Before: The car is moving at a velocity of +25.0 m/s. This is shown as a rightward-moving horizontal arrow above the car. The truck is moving at a velocity of +20.0 m/s. This is shown as a rightward-moving horizontal arrow, shorter than that of the car, above the truck. After: The car is shown crashing into the back of the truck. At this point, the velocity of the car is shown to be +18.0 m/s. This is shown as a rightward-moving horizontal arrow above the car. The velocity of the truck is shown to be v.
