Answer:
The speed of the bullet is 220.6 m/s.
Step-by-step explanation:
Given that,
Distance = 64 cm
Angular displacement = 20.3°
Rotational speed = 1165 rev/min
We need to calculate the time
Using formula of angular displacement


Put the value into the formula


We need to calculate the speed of the bullet
Using formula of speed

Put the value into the formula


Hence, The speed of the bullet is 220.6 m/s.
