A wheel rotates about a fixed axis with a constant angular acceleration of 4.0 rad/s2 . The diameter of the wheel is 40 cm. What is the linear speed of a point on the rim of this wheel at an instant when that point has a total linear acceleration with a magnitude of 1.2 m/s2?
 a. 39 cm/s
  b. 42 cm/s
  c. 45 cm/s
  d. 35 cm/s
  e. 53 cm/s

Question 2
