A 92.2 g blue jay flies through the trees in order to land at a bird feeder. If it flies with a constant speed of 24.0 km/h and makes a tight horizontal turn with a radius of 3.50 m, how much centripetal force must its wings exert to
make the turn?
Gives
We know that
Central petal force
M=92.2g
V=25km/h
r=3.50m
"F=\\frac{MV^2}{r}"
"F=\\frac{92.2\\times10^{-3}\\times{\\frac{24^2\\times1000^2}{3600^2}}}{3.50}"
F=1.170N
