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.........$m/{s^2}$

A

$8$

B

$2$

C

$4$

D

$0.5$

Solution

(b)$F = m \times a$, If force is constant then $a \propto \frac{1}{m}$. So If mass is doubled then acceleration becomes half.
