Acar has a mass of 900 kg and a truck has a mass of 1800 kg. in which of the following situations would they have the same momentum? the car travels at twice the velocity of the truck. the car and truck travel at the same velocity. the truck has a negative acceleration. the car has a positive acceleration.

The car travels at twice the velocity of the truck.

Explanation:

As we know that momentum is defined as the product of mass and velocity

so here we know

mass of the car = 900 kg

mass of the truck = 1800 kg

now let say that the speed of car =

speed of truck =

so if the momentum of car and truck is same

so we can say that car will move with double the speed of truck

d

explanation:

i think the answer is d. but im not sure!

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
