Answer 1

Answer: The maximum static friction force on the sled is 46.122 Newton

Explanation:

Given Data

Mass of the sled = 53 kg

Coefficient static friction force ($\mu_{S}$) = 0.0888 (No unit)

To find - the Maximum static friction force    

The formula to find the Maximum static friction force $F_{S}^{\max }$  is

Maximum static friction force $F_{S}^{\max }$ = Product of coefficient of static friction force   ($\mu_{S}$) and normal force (η)

$F_{S}^{\max }$  = $\mu_{S}$ × η (Newton)

Formula to calculate the normal force (η) is

Normal force (η) = mass × acceleration due to gravity (Newton)

(where acceleration due to gravity has the constant value of 9.8 m/s²)

Normal force (η) = 53 × 9.8 (Newton)

Normal force (η) = 519.4 (Newton)

Maximum static friction force (  $F_{S}^{\max }$) =0.0888 × 519.4  (Newton)

Maximum static friction force ($F_{S}^{\max }$  ) = 46.122 Newton

The maximum static friction force ( $F_{S}^{\max }$ ) is 46.122 Newton for the sled with mass 53 kg and coefficient of static friction force (η) 0.0888 (no unit).
