(12 points) Police use the formula
v=f(L)=\sqrt(20L), to ewimate the speed of a car, v, in males per hour, based on the length,
L, in feet, of its skid marks when suddenly braking on a dry, mphalt road. a.) (4 pts) Find
f^(-1)(v). Show all your work carefulty! b.) ( 4 pts) Evaluate
f(50). What do each of the mumbers represent in the context of this problem? Give the units. c.) (4 pts) Evaluate
f^(-1)(50). What do each of the numbers represent in the context of this problem? Give the units.
