Question

6 kg wheel; 300 rpm. Fin angular velocity [1] 31.4 rad/sec [2] 3.14 rad/sec [3] 0.314 rad/sec [4] 0.0314 rad/sec

Answer 1

Answer:

(1) 31.4rad/s

Explanation:

300revolution per minute

means wheel rotate 300 cycle in 60 sec

in on cycle it rotate 2pi so it will rotate 2π×300=600π in 60 sec

so it will rotate 600π/60 in one second

so fin angular velocity will be 100π=31.4rad/s
