25 kg
Explanation:
we can calculate the mass of the crate by using the Newton's second law:
[tex]F=ma[/tex]
where
F is the force acting on the crate
m is the mass
a is the acceleration
In this problem, [tex]F=200 N[/tex] and [tex]a=8 m/s^2[/tex], so we can re-arrange the equation above to calculate the mass of the crate:
[tex]m=\frac{F}{a}=\frac{200 N}{8 m/s^2}=25 kg[/tex]
