A shell is fired from a cannon. At the instant the shell is just about to leave the barrel, its velocity relative to the barrel is 3 m/s, while the barrel is swinging upwards with a constant angular velocity of 2 rad/s. The magnitude of the absolute velocity of the shell is

1. 3 m/s
2. 4 m/s
3. 5 m/s
4. 7 m/s

Correct Option: C

ωr = 2 × 2 = 4m/sec
υ_net = √3² + 4² = 5 m / s
