A uniform cylinder of radius 40 cm and mass 28 kg is mounted so as to rotate freely about a horizontal axis that is parallel to
and 6.0 cm from the central longitudinal axis of the cylinder. (a) What is the rotational inertia of the cylinder about the axis of rotation?
1 answer:
Answer:
I' = 2.34 kg.m².
Explanation:
Given ,R= 40 cm = 0.4 m
m = 28 kg
d= 6 cm = 0.06 m
The mass moment of inertia of the cylinder about center given as

By using Parallel axis theorem

Now by putting the values


I'=2.34 kg.m²
There the answer will be 2.34 kg.m².

I feel like it expresses time, but if there is another answer and they say otherwise, then they are probably right.
Hope this helps!

Explanation:
Q = mc∆T
= (0.34 kg)(94 J/kg-°C)(25°C)
= 799 J
Answer:
3
Explanation:
v = v⁰ (its original speed) + a (negative acceleration) X t² (time)
v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)
