B=105 , D= 15

2. You and your friend ride a merry-go round. You sit B cm distance from the center your friend sits B/2 cm from the center. If the angular speed of the system is constant, what can you say about following for you and your friend? a. Who is close to the center? b. Which one has the larger linear speed? Explain why c. How about angular speed? Are they the same or different why? d. Who has larger radial acceleration? e. How about tangential acceleration? f. If the ride starts with zero angular speed and runs with constant angular acceleration of D rad/s2 for B/ 10 s, calculate final angular displacement and linear displacement you and your friend travel
