How fast will an object with a mass of 15 kg accelerate if a force of  75 N is constantly applied to it?

The acceleration is 5 m/s^2.

Explanation:

Newton's 2nd Law gives us the formula that shows the relationship between force, mass, and acceleration. The common way to write the formula is

$F = m \cdot a$

Solving that for acceleration yields

$a = \frac{F}{m}$

Plugging your data into that form of Newton's 2nd, we find that

$a = \frac{75 N}{15 k g} = 5 \frac{N}{\text{kg}} = 5 \frac{m}{s} ^ 2$

I hope this helps,
