A rotating flywheel can be used as a method to store energy. If it is required that such a device be able to store up to a maxim um of 1.00 ×106J when rotating at 400 rad/s, what moment of inertia is required? a. 50 kg⋅m2b. 25 kg⋅m2c. 12.5 kg⋅m2d. 6.3 kg⋅m2
1 answer:
Answer:
Explanation:
Given that
Stored energy ,
Angular speed ,
Lets take moment of inertia of the flywheel = I
As we know that stored energy in the flywheel is given as
Now by putting the values in the above equation we get
Therefore the moment of inertia of the flywheel will be
The answer will be C.

Assuming that reaching a height 0 doesn’t stop the ball, and that it accelerates at 9.8 m/s^2, the ball would be traveling at 0.5 + 0.7*9.8 = 7.36 m/s downwards.
8 meters per second. To find velocity is to divide distance by total time. so 400/50.
