Figure shows the path followed by a NASA airplane in a run designed to simulate low-gravity conditions for a short period of time. Make an argument to show that, if the plane follows a particular parabolic path, the passengers will experience weightlessness.

When the airplane is in the low gravity region, it follows a parabolic path around a point of curvature. The gravity acts on the airplane and the pilot to provide the centripetal, however due to the property of inertia, the pilot will have tendency to be in the same state of motion. The body of pilot experiences two kinds of forces; one is gravitation, pulling him down and the other, a pseudo force, pushing him up.
When the magnitude of the forces balances each other, the pilot experiences no net force, and start feeling weightlessness.

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.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
