Now follow the schematic to understand the symmetry and solution via Lami's theorem.
<u>The weight of the monkey will be balanced equally by the tension in both the vines:</u>
Using Lami's Theorem:
Answer:
The net force acting on the bobsled is 300 N.
Explanation:
Given:
Mass of the bobsled is,
Displacement is,
Initial speed is, m/s
Final speed is, m/s
Net acceleration acting on the bobsled can be determined using the following Newton's equation of motion:
Plug in all the given values and solve for acceleration, .
Now, as per Newton's second law, net force is the product of mass and acceleration. So,
Therefore, the net force acting on the bobsled is 300 N.
Answer:
Estimation: year 1110.
Explanation:
We need to know how much time it takes to move 100 arcseconds if it moves at 0.11 arcsecond per year. Similarly to any velocity equation , where in our case the distances are angular, we will obtain the time by doing:
Which, considering from 2019, the explosion ought to have been observed around 1110 (in reality it was observed by Chinese astronomers in 1054).
