Answer: The answer is B
Explanation: It is staying in a steady speed position
There’s not enough info here i’m sorry
The power of a machine is the work/time ratio for that particular machine
Its the rate of doing work.
Answer:
I = 0.287 MR²
Explanation:
given,
height of the object = 3.5 m
initial velocity = 0 m/s
final velocity = 7.3 m/s
moment of inertia = ?
Using total conservation of mechanical energy
change in potential energy will be equal to change in KE (rotational) and KE(transnational)
PE = KE(transnational) + KE (rotational)

v = r ω




I = 0.287 MR²
Every object will remain at rest
