Answer:

[tex]124\:\mathrm{N}[/tex]

Step-by-step explanation:

From Newton's 2nd Law, we have [tex]\Sigma F=ma[/tex].

What we're given:

  • [tex]m[/tex] of [tex]50+12=\textbf{62\:\mathrm{kg}}[/tex]
  • [tex]a[/tex] of [tex]2\:\mathrm{m/s^2}[/tex]

Substituting given values, we get:

[tex]F=62\cdot 2=\boxed{124\:\mathrm{N}}[/tex]
