Question #13359

A bird of mass 1kg is flying due south at the latitude of 30degree N in the northern hemisphere at a speed of 1m/s.Determine the coriolis force acting on it

Expert's answer

R earth = 6.357[km] = 6357000[m]

at 30°: 898.54154[mph] = 1446.1[km/h] = 401.694444 [m/s]

w = 2πr = 7.27220522 × 10^-5[rad/s]

F(cor) = -2mw X v(rot) = -2(1[kg])(7.27220522 × 10^-5[rad/s]) X( 402[m/s])

F(cor) = - 58.46853 [N]

at 30°: 898.54154[mph] = 1446.1[km/h] = 401.694444 [m/s]

w = 2πr = 7.27220522 × 10^-5[rad/s]

F(cor) = -2mw X v(rot) = -2(1[kg])(7.27220522 × 10^-5[rad/s]) X( 402[m/s])

F(cor) = - 58.46853 [N]
