The Coriolis force (see Section 5-6) is a pseudoforce that occurs in rotating coordinate systems (such as the Earth). The force is given by -2m X V where is the rotational velocity of the Earth and is the velocity of a particle as measured from the Earth's (noninertial) frame of reference. (a) A projectile is launched from the equator due north. The direction of the Coriolis force on this projectile is (A) east. (B) west. (C) up. (D) down. (E) The force is zero. (b) A projectile is launched from the equator due east. The direction of the Coriolis force on this projectile is (A) north. (B) south. (C) up. (D) down. (E) The force is zero. (c) A projectile is launched from the equator vertically up- ward. The direction of the Coriolis force on this projectile is (A) north. (B) south. (C) east. (D) west. (E) The force is zero.
