Question

What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?

Answer 1

Explanation:

Given that,

Mass of a car, m = 1200 kg

Acceleration of the car, a = 35 m/s²

The force acting on the car is given by :

F = ma

F = 1200 kg × 35 m/s²

= 42000  N

If the force is 30,600 N, then acecleration is given by :

$a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2$

Hence, this is the required solution.
