Question

The same force is applied to two different cars, each of which accelerates from rest in the same amount of time. Car A has a larger mass than Car B. Which car has a greater acceleration, and which has a greater momentum?

They have the same acceleration and momentum.

Car A has a larger acceleration and momentum.

They have the same acceleration and Car A has a larger momentum.

Car B has a larger acceleration and momentum.

Car B has a larger acceleration and they have the same momentum.

They have the same acceleration and momentum.

Car A has a larger acceleration and momentum.

They have the same acceleration and Car A has a larger momentum.

Car B has a larger acceleration and momentum.

Car B has a larger acceleration and they have the same momentum.

Explanation / Answer

Since, car A has larger mass, its acceleration will be less. As, acceleration = force/mass

and, momentum is just force*time

Hence,

(E) car B has larger acceleration and they have same momentum.
