Question

How fast will an object with a mass of `8 kg` accelerate if a force of `23 N` is constantly applied to it?

Answer 1

We use `F=ma` to solve this problem. The acceleration in this case is `3` `ms^-2`.

Explanation:

We know `m = 8` `kg, F = 23` `N`;

Solve for a:

`a = F/m = (23N)/(8kg) = 23/8 = 2.875` `ms^-2`

Round the answer to the same number of significant digits we have in the data given, which yields an answer of `3` `ms^-2`.
