Answer:
69.66 rad/s
Explanation:
Suppose the handle of the crank is L = 1 m long. We can calculate the torque:
T = F*L = 258*1 = 258 Nm
Then the angular momentum is given to the handle within 0.27 seconds is
rad/s
Answer:
power is given by work done divide time taken
P=w/t
therefore Pt=w
270x42=11,340.J
I think it would be that they have long wavelengths
