Answer:
ω = 5.41 rad/s
Explanation:
Since the rod is rotating around its axis, angular momentum will play part in this question.
The conservation of angular momentum implies that
So, the initial angular momentum is
The final angular momentum includes the rod and the bullet together. So,
It is very important to note down all the details that are given in the question. Based on these details the answer can be derived.
Initial velocity of the car (V1) = 0 meters/second
Final velocity of the car (V2) = 40 meters/second
Initial time (T1) = 0 Second
Final time (T2) = 60 seconds (In this case we have converted 1 minute into 60 seconds for the ease of calculation.
Then
Average acceleration = (V2 - V1)/ (T2 - T1) m/s^2
= (40 - 0)/(60 - 0) m/s^2
= 40/60 m/s^2
= 2/3 m/s^2
= 0.67 m/s^2
So the average acceleration of the car is 0.67 meters/second square.
Well from a non professional standpoint, an athlete-or any other individual, can stretch to relax his/her muscles. Another easy method of muscle relaxation, is icing. Icing your muscles can help release tension in your muscle ligaments.
The answer is actually True, I just took the test and it was correct.
