Two bumper cars are driving directly toward one another. The first car, mass m1 = 150 kg, is moving with velocity 6 m/s to the right and the second car, mass m2 = 200 kg, is moving with velocity 4 m/s to the left.
(a) What is the total momentum of the system (magnitude and direction)?
The two cars collide, and after the collision the first car has stopped.
(b) What is the velocity (magnitude and direction) of the second car?

The angle between the electric field vector and the vector normal to the rectangular plane is 65.0 degrees. Illustrate what is the electric flux through the rectangle?
An object at rest explodes into three pieces of equal masses. One moves east at 23 m/s, while the second piece moves northwest at 14 m/s. Estimate the velocity of the third piece? Suppose each piece has a mass of 2 kg.
They stick together after the collision and are going 10 m/s after the collision. If they skid for 6seconds before stopping, how far did they skid?
