A wheel has a decoration mounted 20 cm from the axis of the 700 mm wheel. An observer notices that the wheel makes 5 turns every second. Calculate the speed (in m/s) and net acceleration of the decoration.

• A. v = 6.28 m/s
  a_r = 197 m/s²
• B. v = 31.4 m/s
  a_r = 4930 m/s²
• C. v = 31.4 m/s
  a_r = 197 m/s²
• D. v = 6.28 m/s
  a_r = 7.88 m/s²
• E. v = 0.159 m/s
  a_r = 0.0319 m/s²
• F. v = 0.159 m/s
  a_r = 0.796 m/s²

Answer: (A)
