Suppose your vehicle’s speedometer is geared to accurately give your speed only using a certain tire size: 17” diameter wheels (the metal part) and a 6.5” tires (thickness of rubber part).

a. If your vehicle’s instruments are properly calibrated, how many times should your tire rotate per second if you are travelling at 55 miles per hour?

b. Now find the angular speed from part a.

c. Suppose you bought new 7.1” tires for your 17” diameter wheels. You took the for a test run and drove at a constant speed of 55 miles per hour (according to your vehicle’s instrument). However, a law enforcement officer stopped you and claimed that you were speeding in a 55 miles per hour zone. How fast did the officer’s radar clock you at, in miles per hour?

Suppose there are only two firms serving your market with the high-speed Internet access. Market demand is estimated to be P = 40 – 5(Q1 + Q2). Each firm’s marginal cost is $20. Suppose each firm maximizes its own profit, treating the other’s quantity as constant. Find an expression for firm 1’s optimal output as it depends on firm 2’s. In equilibrium, what common levels of output will each firm supply? b. Suppose the two firms decide to collude in...
