Answer:
The answer is number 2 :)
Answer:
0.011 N-m
Explanation:
Given that
The mass of a solid cylinder, m = 30 kg
The radius of the cylinder, r = 0.18 m
The acceleration of the cylinder,
It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :
Where
I is the moment of inertia of the cylinder,
For cylinder,
So,
So, the required torque on the cylinder is 0.011 N-m.
The problem is a free fall problem as the camera drops. The vertical velocity is zero. It is the action of gravity that takes place here. To calculate the time it takes to reach the ground, we do as follows:
t = √2y/g = √(2)(70)/9.81 = 3.78 s
The velocity as it impacts the ground would be,
v = √2gy = 37.04 m/s
Hope this helps.
Here’s the answer, idk, it might be correct
