Answer:

[tex]\huge\boxed{\sf F = 120 \ N}[/tex]

Explanation:

Given data:

Mass = m = 80 kg

Initial velocity = [tex]V_i[/tex] = 0 m/s

Final velocity = [tex]V_f[/tex] = 6 m/s

Time = t = 4 s

Required:

Force = F = ?

Formula:

[tex]\displaystyle F=\frac{m(v_f-v_i)}{t}[/tex]

Solution:

Put the given data in the above formula.

Finding force.

[tex]\displaystyle F=\frac{80(6-0)}{4} \\\\F = \frac{80(6)}{4} \\\\F = 20(6)\\\\F = 120 \ N\\\\\rule[225]{225}{2}[/tex]
