Answer:
Magnitude force of friction is 235.2 N
Explanation:
The force of friction is the product of weight and the coefficient of static friction
The force have to be bigger than 200N because it don't move
∑F= [tex]F_{n} - F_{fr}[/tex]
[tex]F_{fr} = u*m*g\\F_{fr} = 0.80*30kg*9.8 \frac{m}{s^{2} } \\F_{fr} = 235.2 \frac{kg*m}{s^{2} } \\F_{fr} = 235.2 }[/tex] N
