Question

1. Two learners want to confirm the principle of conservation of momentum for an isolated system. Two trolleys with identical dimensions but masses m and a 1/2m with a spring-loaded plunger between them, are placed on a horizontal surface. When the spring is released, it takes trolleys x only 0.5 s to reach the barrier, which is 100 mm away. Trolley y takes the same time to cover 200 mm to the other barrier. Calculate the average speed of trolley x and Y respectively show all calculations and work in basic SI units.2. Calculate the total momentum after the release of the spring.

Answer 1

Given:

Mass of trolley x = m

Mass of trolley Y = 1/2m

Distance of trolley X = 100 mm

Distance of trolley Y = 200 mm

Let's solve for the following:

• (a). Calculate the average speed of trolley x and Y respectively show all calculations and work in basic SI units.

Apply the law of conservation of momentum:
