Question

Step by step work starting with the formula.

Q1.

Calculate the centrifugal force acting on a parcel of air of mass 10.0 kg having a radius of 200 cm moving at a velocity of 5.0 m/sec². Centrifugal acceleration is v² divided by r, F = m x a^, where v is the wind speed and r is the radius of curvature.

Q2.

How much pressure is exerted on a tree by a wind blowing at velocity v = 90.0 m/sec? The mean density of air at sea level is 1.225 kg/m³. Hint: Rate of change of momentum = Applied force; mass x velocity = Force.
