Physics
A car of mass 1500 kg moving at 20 m/s collides with a stationary truck of mass 3000 kg. After the collision, the car is observed to move backward at 5 m/s. Calculate the velocity of the truck after the collision.
A bullet of mass 0.02 kg is fired at 300 m/s into a stationary block of mass 2 kg. If they move together after collision, what is their final velocity?
Which of the following describes an elastic collision?
A flowchart is provided with steps to identify collision types based on momentum and energy conservation. If a collision conserves momentum but not kinetic energy, which branch should the flowchart follow?
A meteor impacts the Earth and leaves a crater without bouncing back. What real-world implication does this suggest?
