A 2000 kg truck moving at 15 m/s collides with a stationary car of 800 kg. Both vehicles lock together after the collision. What is their final speed?
💡 Hint: Set up the momentum equation before and after.
Two objects A (mass 3 kg) and B (mass 5 kg) collide. Initially, A moves at 4 m/s, and B moves at -2 m/s. After the collision, A moves at 3 m/s. What is the velocity of B after the collision?
💡 Hint: Setup the conservation equation to find the unknown velocity.
