Question
Car a of mass m a = 2000 kg is moving to the right at 10 m/s when it collides with and sticks to a second car b of mass m b = 3000 kg moving to the left at 5 m/s.
What is the final velocity of the cars after they stick together?
Expert Solution
Step 1
Given data
- The mass of car A is given as mA = 2000 kg.
- The initial velocity of the car A moving towards right is given as uA = 10 m/s.
- The mass of car B is given as mB = 3000 kg.
- The initial velocity of the car B moving towards right is given as uB = -5 m/s.
