Explanation:
The given data is as follows.
M = 35 kg, radius (r) = 2.2 m,
m = 17 kg, = 11 rad/s
We assume that will be the final angular speed.
Now, according to the conservation of angular momentum.
or,
Putting the given values into the above formula as follows.
or,
=
= 7.58 rad/s
Thus, we can conclude that the angular speed of the clay and turntable is 7.58 rad/s.

Answer:
22.47 %
Explanation:
v 1 = 328 m/s, v 2 = 363 m/s
We know that the velocity of a wave in a stretch string is directly proportional to the square root of the tension in the string.
Percentage increase in the tension
= \left ( \frac{1}{0.8165}-1 \right )\times 100
= 22.47 %
Answer:
(a)
(b)
Explanation:
Given data
The angular velocity of two cylinders ω=257 rad/s
The mass of the two cylinders m=2.88 kg
The radius of small cylinder r₁=0.319 m
The radius of larger cylinder r₂=0.605 m
For Part (a)
The rotational kinetic energy of the cylinder is given by:
Where I is rotational of inertia of solid cylinder about its central axis.
So
Substitute the given values
So
For Part (b)
Substitute the given values
