The mechanical advantage of using this pulley system is equal to the amount of force used on the broomsticks. I used work times distance and the total distance was 15. I hope I answered this right lol!
Answer:
The position function is
.
Explanation:
Given that,
Acceleration 
Initial velocity 
Initial displacement 
We know that,
The acceleration is the rate of change of velocity of the particle.

The velocity is the rate of change of position of the particle

We need to calculate the the position
The acceleration is



On integration both side


At t = 0


Now, On integration again both side


At t = 0



Hence, The position function is
.
Answer:
the mass should be bring closer to the point about which we are finding torque
Explanation:
τ = Σr × F = rmg
where m is the mass, g is acceleration due to gravity, and r is the distance
Torque is directly proportional to -
1.mass, m , of object
2. distance, r, of the mass from the point about which we are finding the torque.
So if we increase or decrease them then the torque will also increase or decrease.
So if we increase the mass the torque will increase but since we have to maintain same torque therefore we have to decrease the distance of mass from the point about which we are finding torque.
Therefore the mass should be bring closer to the point about which we are finding torque.
28 times stronger than the force of gravity on the surface of the Earth.
