Determining the pressure difference
A hurricane wind blows across a 7.0 m multiplied by 10.0 m flat roof at a speed of 120 km/hr. (Take the density of air to be 1.28 kg/m3.)
(a) What is the pressure difference?
(b) How much force is exerted on the roof?

An electron in a cathode-ray tube is traveling horizontally at 2.60×109 cm/s when deflection plates give it an upward acceleration of 5.30 × 1017 cm/s^2.
A reaction vessel of volume 20.0 L contains 5.0 mol of nitrogen gas, 3.0 mol of hydrogen gas, and 2.5 mol of oxygen gas at 298 K initially. The gases react forming NH3(g) ammonia and H2O(l) water.
For each of the motions described below, determine the algebraic sign (+, -, or 0) of the velocity and acceleration of the object at the time specified. For all of the motions, the positive y axis is upward.
It may be assumed that the expansion is reversible and adiabatic. What was the initial pressure in the cylinder and how much work is done by the water?
