Explanation:
may I ask what it is on because I might be able to help out
a) 6.25 rad/s
The law of conservation of angular momentum states that the angular momentum must be conserved.
The angular momentum is given by:
where
I is the moment of inertia
is the angular speed
Since the angular momentum must be conserved, we can write
where we have
is the initial moment of inertia
is the initial angular speed
is the final moment of inertia
is the final angular speed
Solving for , we find
b) 28.1 J and 35.2 J
The rotational kinetic energy is given by
where
I is the moment of inertia
is the angular speed
Applying the formula, we have:
- Initial kinetic energy:
- Final kinetic energy:
Answer:
the weight of alien is 200 newtons
Explanation:
The computation of the alien weight is shown below:
Given that
Acceleration = 20m/sec^2
And, the mass is 10 kg
So, the weight of alien is
= 20 × 10
= 200 newtons
hence, the weight of alien is 200 newtons
Answer:
I'm a little confused on what your asking so I just filled out the form
Explanation:
Date:12/20/19
warm up: 10 minutes
cool-down: 5 minutes
Type of activity: Flexibility
Description of activity and time:
I put one arm up bended behind my back and one hand down, also bended behind my back and tried to touch my hands to each other while on my back I tried to see if my fingers overlap.
Intensity level: Moderate
total time: 20 minutes
( I hope this is correct and I didn't misunderstand your question if so I'll redo it, I think you did to do the test so you can measure if it is a negative or positive score and measure how much )
