Answer:
1.034m/s
Explanation:
We define the two moments to develop the problem. The first before the collision will be determined by the center of velocity mass, while the second by the momentum preservation. Our values are given by,
<em>Part A)</em> We apply the center of mass for velocity in this case, the equation is given by,
Substituting,
Part B)
For the Part B we need to apply conserving momentum equation, this formula is given by,
Where here is the velocity after the collision.

Answer:
<em>Angular displacement=68.25 rad</em>
Explanation:
<u>Circular Motion</u>
If the angular speed varies from ωo to ωf in a time t, then the angular acceleration is given by:
The angular displacement is given by:
The wheel decelerates from ωo=13.5 rad/s to ωf=6 rad/s in t=7 s, thus:
Thus, the angular displacement is:
Angular displacement=68.25 rad
If it is not exposed to sunlight often... then it might not be able to produce sufficient amounts
Corrosive. It’s something that tends to cause corrosion, and it means to destroy or damage things slowly by chemical action.
