A 12-kg projectile is launched vertically upward with an initial speed of 35 m/s from a football field in Minneapolis, MN. (a) Calculate the magnitude and direction of the Coriolis force (see Multiple Choice question 8 and Section 5-6) 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? (c) Will the projectile return to the original launch point? If not, in which direction will it land relative to the launch point?

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
