![a=40\ m/s^2](https://img.qammunity.org/2022/formulas/physics/high-school/egexo21fnq2g163pb0jvx3wdm5xcp26gn9.png)
Step-by-step explanation:
Given that,
Initial speed of a shuttlecock, u = 30 m/s
Final speed of the shuttlecock, v = 10 m/s
Time, t = 0.5 s
We need to find its average acceleration. The acceleration of an object is equal to the change in speed divided by time taken. It is given by :
![a=(v-u)/(t)\\\\a=(10-30)/(0.5)\\\\a=-40\ m/s^2](https://img.qammunity.org/2022/formulas/physics/high-school/nqy0n9x5xbwo0pobl3g19edmm5kb0jbz2l.png)
So, the average acceleration of badminton shuttlecock is
