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]
