Question

A force F1 of 500 N is required to push a car of mass 1000 kg slowly at constant speed on a levelled road. If a force F2 of 1000 N is applied, the acceleration of the car will be (A) zero (B)  1.5 m/s2  (C)  1.0 m/s2  (D)  0.5 m/s2

We know that a force of 500 N does not produce any acceleration because it pushes the car slowly at constant speed. Out of 1000 N force, only 500 N produces acceleration, the mass is 1000 kg, so Acceleration =( textforce/ textmass) =(500/1000)=0.5 m/s2

Q. A force $F_{1}$ of $500 N$ is required to push a car of mass $1000 k g$ slowly at constant speed on a levelled road. If a force $F_{2}$ of $1000 N$ is applied, the acceleration of the car will be

zero

$1.5 m / s^{2}$

$1.0 m / s^{2}$

$0.5 m / s^{2}$

We know that a force of $500 N$ does not produce any acceleration because it pushes the car slowly at constant speed. Out of $1000 N$ force, only $500 N$ produces acceleration, the mass is $1000 k g$ ,
so Acceleration $= \frac{force}{mass}$
$= \frac{500}{1000} = 0.5 m / s^{2}$

Q. A force F1​ of 500N is required to push a car of mass 1000kg slowly at constant speed on a levelled road. If a force F2​ of 1000N is applied, the acceleration of the car will be

zero

1.5m/s2

1.0m/s2

0.5m/s2

We know that a force of 500N does not produce any acceleration because it pushes the car slowly at constant speed. Out of 1000N force, only 500N produces acceleration, the mass is 1000kg, so Acceleration =massforce​ =1000500​=0.5m/s2
