Question

6. Which has the least momentum?
7. In which situation will a delivery truck have a greater momentum than a tourist bus?
a. The delivery truck has twice the mass and speed of the tourist bus
b. The delivery truck is slower but has the same mass of the tourist bus
C. The tourist bus is more massive than the truck but they move with the same speed
d. The mass and speed of the tourist bus are larger than the mass and speed of the delivery truck​

Answer 1

A. The delivery truck has twice the mass and speed of the tourist bus.

Explanation:

as we know,

P=mv

Where

P= momentum

M= mass

V= Velocity

So more would be the mass and velocity, more would be the momentum.

Therefore,

Delivery truck would have more momentum when it would have twice the mass and speed of the tourist bus.

Answer 2

Answer:Option d is your answer

As speed and mass are less in that case momentum is less

Explanation:

Momentum is a vector quantity, given by the product of an object's mass and velocity. If the velocity of the object is negative, i.e. the object is traveling in what has been chosen as the negative direction, the momentum will also be negative.

Truck have more momentum, because you a the bus are travelling at the same speed, but truck have much more mass. Truck therefore have more inertia, and require much more force than the bus to come to a stop.

P=mv

Where

P= momentum

M= mass

V= Velocity

P=m$v^{2}$

So more would be the mass and velocity, more would be the momentum.

Therefore,Delivery truck would have more momentum when it would have twice themass and speed of the tourist bus.
