Answer:
3.5
Explanation:
= Straight moment of inertia = 14 kgm²
= Tucked moment of inertia = 4 kgm²
= Straight angular velocity
= Tucked angular velocity
In this system the angular momentum is conserved
The factor is 3.5
Answer:mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle in the absence of friction
Explanation:
The mechanical advantage of a wheel and axle is equal to the ratio of the radius of the wheel to the radius of the axle in the absence of friction
The SI unit for mass is the kilogram, the Imperial unit is the slug, and the unit used in the US is the pound.
Answer:
4.62 s
Explanation:
We are given that
Initial angular speed,
Substitute the values
Hence, the wheel takes 4.62 s to come to rest.
It’s initial velocity will be Constant velocity because it never sped up it just went place to place
