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).

Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
The kilogram is the SI unit of mass (kg). In science and technology, a body's weight in a given reference frame is the force that causes it to accelerate at a rate equal to the local acceleration of free fall in that frame.
For instance, a kilogram mass weighs around 2.2 pounds at the surface of the planet. However, the same kilogram mass would weigh just about 0.8 pounds on Mars and about 5.5 pounds on Jupiter.
An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.

The length of the semi-major axis is calculated as follows:

where $, $G=6.67 \times 10^{-1} \mathrm{~m}^3 / \mathrm{kgs}$$

$M=1.99 \times 10^{30} \mathrm{~kg}=$ mass of sur

$m=1.20 \times 10^{10} \mathrm{~kg}$ - a mass of the comet

$\begin{aligned}\therefore \quad \text { At aphelion, } r &=50 \times U \\&=50 \times 1.496 \times 10^{11} \mathrm{~m} . \\U=-\frac{6.67 \times 10^{-11} \times \mathrm{m} 1.99 \times 10^{30} \times 1.20 \times 10^{10}}{50 \times 1.496 \times 10^{11}} \\U=-2.13 \times 10^{17} \mathrm{~J} .\end{aligned}$

$U=-2.13 \times 10^{17} \mathrm{~J} .\end{aligned}$
