A 750 kg car is stalled on an icy road during a snowstorm. A 1000 kg car traveling eastbound at 12 m/s collides with the rear of the stalled car. After being hit, the 750 kg car slides on the ice at 4 m/s in a direction 30° north of east.

Review I Constants
A 750 kg car is stalled on an icy
road during a snowstorm. A
1000 kg car traveling eastbound at
12 m/s Collides with the rear of the
stalled car. After being hit, the
750 kg car slides on the ice at
4 m/s in a direction 30° north of
east.
Part A

Part B
What is the direction of the
velocity of the 1000 kg car after
the collision?
Express your answer in
degrees measured from the
east direction. Enter positive
value if the direction is north
of east and negative value if
the direction is south of east.
