The average angular velocity during the dive is 10.78 rad/sec.
Given,
displacement of the diver = 10.4m
as the diver falls freely then the acceleration will be g=9.8
To find average angular velocity during dive use formula,
where, θ=angular displacement and t= time taken to reach water
the diver makes 2.5 revolutions, here 1 revolution is 2π radians then total angular displacement is
θ=2.5* 2π=15.7 radian
To find time taken, use formula
here u=initial velocity=0
s=displacement of diver=10.4m
angular velocity,
Thus, the average angular velocity during the dive is 10.78 rad/sec.
