Answer:
1.
2.
3.
4. α = 59.05°
5.
6. α = 59.05°
Explanation:
The position of the center of mass 1s before the collision is:
where
; ;
; ;
Replacing these values:
where
; ;
; ;
Replacing these values:
The velocity of their center of mass is:
where
; ;
; ;
Replacing these values:
where
; ;
; ;
Replacing these values:
So, the magnitude of the velocity is:
The angle of the velocity is:
Since on any collision, the velocity of the center of mass is preserved, then the velocity after the collision is the same as the previously calculated value of 16.66m/s at 59.0° due north of east
Answer:
(D) the sphere
Explanation:
The bodies given are Disk and Solid sphere (uniform sphere)
Moment of inertia of the bodies are
I(disk) =
I(sphere) =
Since the moment of inertia of sphere is less than that of disk, therefore sphere will reach the bottom first.
It is based on their state like population, literacy and poverty it varies from state to state, country to country
Potential energy is energy stored due to its position. Thermal energy is energy released as heat
