A 12-kg projectile is launched vertically upward with an initial speed of 35 m/s from a football field in Minneapolis, MN. Required:
a. Calculate the magnitude and direction of the Coriolis force on the projectile shortly after the projectile is launched.
b. What is the approximate direction of the Coriolis force on the projectile while the projectile is heading back toward the Earth?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l
