A kid is on a stationary sled, on

gregori [183]

The mass of the kid and the sled is 50.0 kg

Explanation:

The sled starts to move when the force applied becomes larger than the maximum force of static friction, which is given by

$F_{max} = \mu_s mg$

where

$\mu_s$ is the coefficient of static friction

m is the mass of the kid + the sled

$g=9.8 m/s^2$ is the acceleration of gravity

Here the sled starts moving when the force applied is 61.2 N, so

$F_{max}=61.2 N$

And we also know

$\mu_s = 0.125$

Therefore, we can find the mass of the kid and the sled by re-arranging the equation:

$m=\frac{F_{max}}{\mu_s g}=\frac{61.2}{(0.125)(9.8)}=50.0 kg$

Which best compares the gravitational force and the strong force ?

Elan Coil [88]

The heavier the body is, the stronger its gravitational pull. Example, the Milky Way Galaxy has a gravitational pull because of the heavenly bodies such as stars and planets are surrounding it. A strong force is exerted if the mass of another body is bigger than the other body.

Answer:

One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2). The pascal is also used to measure stress, specifically tectonic stress in the Earth's plates.
