Momentum is mass multiplied by velocity - so it is proportional to the velocity. If the velocity triples then so does the momentum
Momentum is directly proportional to the velocity. Thrice the velocity means thrice the momentum.
The momentum of the bus would increase by a factor of three since momentum is directly proportional to velocity. The bus's momentum is equal to the product of its mass and velocity.
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
EXPLANATION:- We know that:- K.E = 1/2 m v^2 => K.E is directly proportional to the square of velocity. Conclusion:- If velocity becomes tripled than K.E. becomes Nine times to its initial value.

When something increases in velocity, its momentum would increase because momentum is equal to its mass * velocity. This means that the momentum and velocity are proportional, so twice the velocity is twice the momentum, and so on.

The momentum of the passenger bus would depend on its mass and velocity. To calculate it, multiply the mass of the bus by its velocity. If the velocity is troubled, the momentum would change accordingly, decreasing or increasing depending on the direction and magnitude of the velocity change.
That would depend on their velocity (speed with direction), since the formula for momentum is momentum=Mass*Velocity. If they are moving at the same Velocity, the heavier of the two would have greater momentum.
The answer is velocity.
An object with a small mass and low velocity would have the least momentum. Momentum is the product of an object's mass and velocity, so a combination of low mass and low velocity would result in the least momentum.
Momentum = mass x velocity. If you divide out the velocity you get mass.
