#### Answer

(a) Greater than. (b) Choice II.

#### Work Step by Step

According to Newton's Third Law, all forces cause an equal and opposite force. Since the forces are the same and $F=ma$, the acceleration must be equal to $a=\frac{F}{m}$. Therefore, as mass increases and force remains the same, the acceleration decreases. Since the car has less mass than the truck, the car will have larger acceleration.
