Concept explainers

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

define linear momentum and calculate the momentum of a mass of 10 kg travelling at 30 miles/hours . a stationary mass of 100g is struck by a mass of 25 g moving at 10m/s assuming the collision is perfectly elastic, What is the velocity of the two masses after the impact? Repeat the calculation assuming the collision is perfectly inelastic?
