The minimum force required to start this block moving is 370 N.
The given parameters;
- weight of the block, W = 500 N
- coefficient of static friction, [tex]\mu_s[/tex] = 0.74
The minimum force required to start this block moving is calculated as follows;
[tex]F= \mu_s F_n[/tex]
where;
[tex]F_n[/tex] is the normal force on the block which is equal to the weight of the block
[tex]F= \mu_s F_n \\\\F= \mu_s W\\\\F = 0.74 \times 500 \\\\F= 370 \ N[/tex]
Thus, the minimum force required to start this block moving is 370 N.
