Solve the unknown and confirm your answer of static friction using the Phet Simulation software. (Use the part of with Acceleration in Phet Simulation)
Suppose the supply of lemonade is given by Q= 40p were q is measured in pints and p is measured in cents per pint and the demand for lemonade is given by Q=5000-10p. Now suppose bumper weather conditions improve the harvest of lemons so producers increase the quantity supplied of lemonade by 200 pints at every price. What are the equilibrium P and Q for a lemonade after the bumper weather conditions
