Car A has a mass of 1,500 kg and travels to the right with a
speed of 20 m/s. Car B initially travels to the left with a speed
of 10 m/s. After the vehicles collide, they stick together, moving
left with a common speed of 5 m/s. What is the mass of Car B?

Physics 101 Mechanics

A railroad engine moves forward along a straight section of
track for a distance of 100 m due west at a constant speed of 5
m/sec. It then reverses its direction and travels 40 m due east at
a constant speed of 4 m/sec. The time required for it to slow down
and reverse is very short due to the small speeds. What is the
average velocity of the engine?

Physics 101 Mechanics

Two boats are anchored in the harbor, separated by a horizontal distance of 20 m. The boats bob up and down as the waves enter the harbor. When the first boat is at its highest point, the second is also at its highest point and there is one wave crest between them. Each boat makes exactly 5 complete up-and-down cycles every 30 s. The vertical distance between a boat's highest and lowest point is 2.2 m.
