Practice Problem: The Mini-Golf Windmill

Professor Dave uses a mini golf scenario to explain physics concepts. He describes a windmill obstacle with rotating blades and calculates the optimal ball velocity to pass through it. By applying linear and rotational kinematics, he determines the ball will pass unscathed. The tutorial emphasizes practical physics applications.

What is the angular speed of the windmill blades in the mini golf scenario?

• 100 degrees per second

What is the width of each windmill blade?

• 1/5 meter

• 1/4 meter

• 1/3 meter

• 1/2 meter

Which two types of kinematics are necessary to solve the mini golf problem?
