State the principle of conservation of linear momentum in words. Calculate the distance travelled by trolley B in 1.3 s. Calculate the time it took the spring to extend to its natural length. How does the magnitude of the velocity of trolley C compare to the magnitude of the velocity of trolley B after the spring has fallen to the track? Write only GREATER THAN, LESS THAN, or EQUAL TO. Explain the answer.
Understand the Problem
The question involves concepts of physics, specifically the principles of linear momentum and spring dynamics. It asks to state a principle, perform calculations regarding the motion of trolleys, and analyze the relationship between the velocities of different trolleys after certain interactions with a spring.
Answer
Velocity of trolley C is LESS THAN trolley B.
The principle of conservation of linear momentum states that the total linear momentum of a closed system remains constant if no external forces act on it. The distance traveled by trolley B, and the time it took for the spring to extend should be calculated using provided data. Trolley C's velocity is LESS THAN trolley B's after the spring falls because its mass is larger, assuming constant force.

The principle of conservation of linear momentum states that the total linear momentum of a closed system remains constant if no external forces act on it. The distance traveled by trolley B, and the time it took for the spring to extend should be calculated using provided data. Trolley C's velocity is LESS THAN trolley B's after the spring falls because its mass is larger, assuming constant force.
More Information
In a closed system, the momentum before and after an interaction remains the same. With a larger mass, trolley C experiences less velocity change for the same force applied.
Tips
When using s = ut + (1/2)at^2, ensure the correct initial values and determine acceleration using known forces.
