Suppose, the same angular momentum is transferred to two rotating bodies of different moment of inertia , how will you compare t
1 answer:
Answer:
As per the law of conservation of angular momentum, the angular velocity will be higher for the body with a lower moment of inertia and vice versa.
Explanation:
Angular momentum L of a body is given by:
Now when the same angular momentum is transferred to two different bodies with different moment of inertia, the body with a higher moment of inertia will have lower angular velocity and vice versa.

You want to draw a free body diagram of the forces on the sled in the horizontal x-direction.
If you visualize the system in an x-y coordinate plane, the force along the x-direction is the angle it makes with the x-axis multiples by the force.
The angle made with the x-axis is cosine of the angle theta.
Please see picture attached.

At 10 m/s, it will take
(2 m)/(10 m/s) = 0.2 s
to bridge the gap.

From the exercise we have:
To find the velocity after 2.4s we need to use the following formula:
The negative sign means that the kit is going down.
