PART ONE In a 52 s interval, 381 hailstones strike a glass window of area 1.124 m^2at an angle 43◦to the window surface. Each hailstone has a mass of 5 g and speed of 6 m/s. If the collisions are elastic, find the average force on the window. Answer in units of N.
PART TWO Find the pressure on the window. Answer in units of N/m^2.

How will each of the following changes in demand and/or supply affect equilibrium price and equilibrium quantity in a competitive market; that is, do price and quantity increase or decrease, or are the answers indeterminate because they depend on the magnitudes of the shifts?
