Question

What is the mass of a crate with a net force of 300N and accelerate it by 0.750 m/s²

Answer 1

According to the second Newton's law, the mass is given as follows:

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

where $F = 300N$ is the net force, and $a= 0.750m/s^2$ is the acceleration. Thus, obtain:

$$m = \dfrac{300N}{0.750m/s^2} = 400kg$$

Answer. 400 kg.
