Pitch is related to frequency
KE=1/2 m v^2
KE= .5 x 2kg x 15m/s to the 2nd power
KE=225 km/s
The total momentum should come out to be <span>2.0 x 10^4 kilogram meters/second </span>
Answer:
The magnitude of the applied torque is 
(e) is correct option.
Explanation:
Given that,
Mass of object = 3 kg
Radius of gyration = 0.2 m
Angular acceleration = 0.5 rad/s²
We need to calculate the applied torque
Using formula of torque

Here, I = mk²

Put the value into the formula



Hence, The magnitude of the applied torque is 
acceleration = change in velocity/change in time
so...
a = 20 m/s / 2 seconds
a = 10
hope that helps :)
