Answer:
5.74s
Explanation:
We can first solve for the initial angular velocity using the following formula
Where is the final angular velocity, is the angular acceleration and is the angular displacement
So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be
If an object<span> is slowing down, then its </span>acceleration<span> is in the opposite direction of its motion. ... In Example A, the </span>object<span> is moving in the positive direction (i.e., has a positive </span>velocity<span>) and is speeding up. When an </span>object<span> is speeding up, the </span>acceleration<span> is in the same direction as the </span>velocity<span>.</span>
Answer:
The two dogs sitting here are already poor and ignorant
Force=mass x acceleration
Data:
mass=4 Kg
Force=8 N
8 N=4 kg * a
a=8 N/4 Kg=2 m/s²
answer: the acceleration is 2 m/s²
