As long as they're both on the same planet, the greater mass always has the greater weight. In this question, Object-A has the greater mass, so it weighs more that Object-B does.
Answer:
The average angular acceleration is ![\alpha =125.487 rad /s^2](https://tex.z-dn.net/?f=%5Calpha%20%3D125.487%20rad%20%2Fs%5E2)
Explanation:
From the question we are told that
From the question we are told that
The length of the bat is
\
The initial linear velocity is ![u = 0 m/s](https://tex.z-dn.net/?f=u%20%3D%200%20m%2Fs)
The time is ![t = 0.15s](https://tex.z-dn.net/?f=t%20%3D%200.15s)
The velocity at t is ![v = 16 m/s](https://tex.z-dn.net/?f=v%20%3D%2016%20m%2Fs)
Generally average angular acceleration is mathematically represented as
![\alpha = \frac{w_f - w_o}{t}](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%5Cfrac%7Bw_f%20-%20w_o%7D%7Bt%7D)
Where
is the finial angular velocity which is mathematically evaluated as
![w_f = \frac{v}{l}](https://tex.z-dn.net/?f=w_f%20%3D%20%5Cfrac%7Bv%7D%7Bl%7D)
![w_f = \frac{16}{0.85}](https://tex.z-dn.net/?f=w_f%20%3D%20%5Cfrac%7B16%7D%7B0.85%7D)
![= 18.823 rad/s](https://tex.z-dn.net/?f=%3D%2018.823%20rad%2Fs)
and
is the initial angular velocity which is zero since initial linear velocity is zero
So
![\alpha = \frac{18.823 - 0}{0.15}](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%5Cfrac%7B18.823%20-%200%7D%7B0.15%7D)
![\alpha =125.487 rad /s^2](https://tex.z-dn.net/?f=%5Calpha%20%3D125.487%20rad%20%2Fs%5E2)
