A. What was the average angular speed (degrees/s and rad/s) of the hand? B. What was the average linear speed (m/s) of the hand? C. Are the answers to A and B the same or different? Explain your answer.
11. Which kinematic variables are similar and which are different between the two scenarios; moving your foot alone, and moving your foot with extra mass?
a. How far in degrees did the hand travel during the five rotations? b. How far in radians did the hand travel during the five rotations? (Hint: 180∘=π radians) c. How far in meters did the hand travel during the five rotations? (Hint: circumference of a circle =2∗π∗ radius )
