Question

The mass of a large car is `1000` `kg`. How much force would be required to accelerate the car at a rate of `3` `m``/sec^2`?

Answer 1

`3000N`

Explanation:

newton's 2nd law:
resultant force = mass * acceleration

this is also known as `F = ma`, where `F` is resultant force, `m` is mass and `a` is acceleration.

here, `m = 1000kg` and `a = 3m//s^2`.

`F = ma = 1000kg * 3 m//s^2`

`= 3000N`

hence, the force needed to accelerate the `1000kg` car by `3 m//s^2` is `3000N`.
