Answer:
The angular momentum of the system is 0.00381 kg*m^2/s
Explanation:
The moment of inertia of rod is:
The angular momentum is:
Answer:
35.1688 seconds
Explanation:
M = Mass of sphere = 8200 kg
R = Radius of sphere = 90 cm
F = Force = 30 N
Moment of inertia is given by
Torque is given by
For one rotation
The time taken to rotate the sphere from rest is 35.1688 seconds
Answer:
c) Both the parts will weigh the same
Explanation:
center of gravity is based on weight so if you cut down the center of gravity you would have 2 equal parts
(might be D if it is cutting against the center of gravity)
Answer:
<h2>GIVEN :-</h2>
Initial velocity = 0 × 5/18 = 0 m/s
Final Velocity = 100 × 5/18 = 27.77 m/s
Time = 6 sec
<h2>TO FIND :-</h2>
Acceleration
<h2>SOLUTION :</h2>
We know that
a = v - u/t
a = 27.77 - 0/6
a = 27.77/6
a = 4.6 m/s²
