Question

A force of 200 N is required to push a car of mass 500 kg slowly at constant speed on a level road. If a force of 500 N is applied, the acceleration of the car in (meter/second square ) will be???

Answer 1

When 200 N force is applied on the car, it moves with constant velocity.

Hence, the force of friction from the road is 200 N

Mass of car = 500 kg

Now, the force applied (F) = 500 N

Let the acceleration be a.

According to Newton's second law:

$F_n_e_t = ma$

Force applied - Friction = ma

500 - 200 = 500 × a

$a = \frac{300}{500}$

a = 0.6 m/s^2

Hence, the acceleration of the car is 0.6 m/s^2.
