1. A bicycle wheel spins makes 50 revolutions per
minute. What is the angular speed of the
bicycle?
2. A building that is 30 feet tall casts a shadow on
the ground that is 22 feet long. What is the
angle of elevation of the sun?
If the bicycle wheel has a radius 1.25ft what is
the speed (linear) of the bicycle in feet per
minute?
3. Mr. Fuentes is standing on top of the E building and sees two students who are walking on the ground.
