Answer:
The car's angular speed is 
.
Explanation:
Angular velocity is usually measured with 
, so I'm going to use that to answer your question.
The relationship between tangential velocity and angular velocity (ω) is given by:
Using the values from the question, we get:
Therefore, the car's angular speed is 
.
Hope this helped!
<span>Amplitude is the maximum extent of vibration
As by increasing the amplitude the wave speed ,frequency and wavelength will remain same so it will increase </span><span>the speed of the individual particle in the medium.
This will increase wave energy
so correct option is B
hope it helps</span>
Blu ! The formula is right THERE, IN the question. All you have to do is plug numbers into it.
The formula: Kinetic Energy = 1/2 m v²
' m ' is 2,000 kg
' v ' is 22 m/s
Now pluggum in:
KE = (1/2) (2,000 kg) (22 m/s)²
KE = (1/2) (2,000 kg) (22 m/s x 22 m/s)
KE = (1/2) (2,000 kg) (484 m²/s²)
I'm <u><em>sure</em></u> you can finish it off from this point, and pick the correct choice.
