Answer:

The right solution is "24.39 per sec".

Explanation:

According to the question,

⇒ v=\frac{502.1}{\sqrt{3} }

      =289.9 \ m/s

The time will be:

⇒ t=\frac{d}{v}

      =\frac{2\times 6}{289.9}

      =\frac{12}{289.9}

      =0.041 \ sec

hence,

⇒ N=\frac{1}{t}

        =\frac{1}{0.041}

        =24.39 \ per \ sec

A satellite is spinning at 6.2 rev/s. The satellite consists of a main body in the shape of a solid sphere of radius 2.0 m and m
trapecia [35]

Answer:

627031 kgm^2/s

Explanation:

First convert angular speed from 6.2 rev/s to rad/s knowing that each revolution is 2π rad:

\omega = 6.2 * 2\pi = 38.96 rad/s

The we can calculate the moments of inertia of the satellite by summing up the 2 moments of inertia of the solid sphere and the 2 rods at their ends:

I = I_s + 2I_r

I = \frac{2}{5}MR^2 + 2\frac{1}{3}mL^2

I = \frac{2}{5}10000*2^2 + 2\frac{1}{3}16*3^2

I = 16000 + 96 = 16096 kgm^2

Then the angular momentum is the product of angular velocity and moment of inertia

\omega I = 38.96 * 16096 = 627031 kgm^2/s
