Question

@Abhisar At the start of a race, car X, car Y, and car Z each accelerate from rest. Car X is more massive than car Y, and car Y is more massive than car Z. Over 10 seconds, the average force exerted on each car is identical. After 10 seconds, which car, if any, has the greatest momentum?

Car X
All have the same momentum
Car Y
Car Z

Answer 1

What do you think ?

Answer 2

I fell like it should be the same since the force is the same

Answer 3

Correct !

Answer 4

Force = Rate of change of momentum = Final - Initial momentum/Time

Answer 5

All the cars have same initial momentum = 0, let their final momenta be x, y and Z

Answer 6

Thanks that makes sense now

Answer 7

F=(X-0)/10 , F=(Y-0)/10 and (F=z-0)/10 (wr F is the force which is similar in all cases.). Thus X=Y=Z
