This is just practice, but i still need help. Can someone explain?
If car A and car B have the same acceleration, but car B has three times the mass of car A, what must be true about car A and car B?
a. Car B must have an engine providing more force than car A to match its
acceleration
b. Car A must have an engine providing less force to slow down
c. Car B must be moving on a different course than car A
d. Car A cannot be moving at the same acceleration of Car B unless the masses change

I need help ASAP!
F = ma
since B has greater mass, it must be using more force
since B has greater mass, it must be using more force
Car B must have an engine providing more force than car A to match its acceleration
not sure if this is right. trust me if you want to but sorry if I'm wrong
