Answer:
The final speed of the stone as it lift the ground is 23.86 m/s.
Explanation:
Given that,
Force acting on the rock, F = 3 N
Distance, d = 16 m
Initial speed of the stone, u = 22 m/s
We need to find the rock's speed just as it left the ground. It can be calculated using work energy theorem as :
So, the final speed of the stone as it lift the ground is 23.86 m/s.
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.
