Q. The engine of a car produces acceleration $4\ m/s^{2}$ in the car. If this car pulls another car of same mass, what will be the acceleration produced
A) $8\ m/s^{2}$
B) $2\ m/s^{2}$
C) $4\ m/s^{2}$
D) $1/2\ m/s^{2}$
Explanation
(b) $F = m \times a$, If force is constant then $a \propto \frac{1}{m}$
So If mass is doubled then acceleration becomes half
