(B) According to Newton's second law of motion,the force $F$ produced by the engine is given by $F = m 	imes a$,where $m$ is the mass and $a$ is the acceleration.Since the force $F$ remains constant,we have $a \propto \frac{1}{m}$.Initially,the mass is $m$ and the acceleration is $a_1 = 4\,m/s^2$.When the car pulls another car of the same mass,the total mass becomes $M = m + m = 2m$.Let the new acceleration be $a_2$. Since $F = m 	imes a_1 = 2m 	imes a_2$,we get $a_2 = \frac{a_1}{2}$.Substituting the value,$a_2 = \frac{4}{2} = 2\,m/s^2$.

The engine of a car produces an acceleration of $4\,m/s^2$ in the car. If this car pulls another car of the same mass,what will be the acceleration produced in $m/s^2$?
