Academics

Q1. A 28-{rm cm}-diameter vertical cylinder is sealed at the top by a frictionless 25 kg piston. The piston is 87 cm above the bottom when the gas temperature is 311^circ C. The air above the piston is at 1.00 {rm atm} pressures.

Q2. A projectile is launched from the top of a cliff above level ground. At launch the projectile is 35 meters above the base of the cliff and has the velocity of 50 meters per second at an angle 37° with horizontal. Air resistance is negligible.

Compute the total time from launch till projectile hits the ground at point c.
