The magnitude of the net force required to bring the mass to a stop is 25 N
Explanation:The mass, m = 40.0 kg
The initial velocity, u = 5.0 m/s
Since the mass comes to a stop in 8.0 seconds
The final velocity, v = 0 m/s
The time, t = 8.0 seconds
The magnitude of the netforce is given by the formula:
[tex]\begin{gathered} F=|\frac{m(v-u)}{t}| \\ F=|\frac{40(0-5)}{8}| \\ F=|\frac{40(-5)}{8}| \\ F=|-\frac{200}{8}| \\ F=|-25| \\ F=25N \end{gathered}[/tex]The magnitude of the net force required to bring the mass to a stop is
25 N
