a) What should be the angular velocity of the earth such that a person of mass 80 kg standing on the earth at the equator would actually fly off the earth? b) A ball of mass 60g is moving due south with a speed of 50 ms⁻¹ at latitude 30ºN. Calculate the magnitude and direction of the coriolis force on the ball.
Introduction This question deals with two different rotational motion concepts: (a) Rotational dynamics of the Earth to find the critical angular velocity at which objects at the equator would become weightless. (b) Coriolis force, which is an apparent force due to Earth’s rotation, affecting moving bodies in a rotating frame. Part (a): Angular Velocity for […]
