A basket ball of radius `R` is spun with an angular. `vecomega=omegahatk` and its `CM` moves with a speed `v`. Find aerodynamic lift experienced by the ball. Assume `=` density of air.

Text Solution

Verified by Experts

The correct Answer is:
`F=2pirhoR^(3)vomega`
`F=(/_\P)A_(eff)` where `A_(eff)=piR^(2)` and `/_\R|P_(1)-P_(2)|`

`/_\P=1/2rho[(v+Romega)^(2)-(v-Romega)^(2)=2Rrhovomega`
Then `F=2pirhoR^(3)vomega`
