Answer:
Angular velocity is same as frequency of oscillation in this case.
ω = x
Explanation:
- write the equation F(r) = -K with angular momentum <em>L</em>
- Get the necessary centripetal acceleration with radius r₀ and make r₀ the subject.
- Write the energy of the orbit in relative to r = 0, and solve for "E".
- Find the second derivative of effective potential to calculate the frequency of small radial oscillations. This is the effective spring constant.
- Solve for effective potential
- ω = x
I know the answer to 1 minute
6000 joule energy
So I assume 30 seconds would be
3000 joule energy
Answer:
By throwing wrenches and screwdrivers away the side of spaceship he might be able to get back.
Explanation:
<em>Theory</em>
<u>The law of conservation of linear momentum</u>
The sum of linear momentum of a closed system under no external unbalance force remains the same.
Here consider the astronaut and the wrenches and screwdrivers as a system.
System in the empty space so no external unbalance force exerted on the astronaut. As the linear momentum is conserved when he throw wrenches and screwdrivers away form the space ship he will gain an equal momentum in the opposite direction. So he gains a certain velocity which he can use to drift towards the spaceship.
