Answer:
220,500 Joules
Explanation:
PE = (75 kg) x (9.8 ) x (300 m)
PE = (735) x (300)
PE = 220,500 Joules
Answer:
Pluck velocity = 83.34 m/s
Explanation:
The initial angular speed of the rod before it was hit,
The angular speed of the rod and pluck rotating together,
The period of rotation, T = 0.736 s
Using the principle of conservation of angular momentum:
We are given with the data that says the probability that a battery will last 10 hr or more is 0.8 and the probability <span>that it will last 15 hr or more is 0.11. In this case, the probability that the battery lasts at least 10 hours and even 15 hrs more is 0.11 / 0.8 or equal to 13.75 percent.</span>
