A roadway is designed for traffic moving at a speed of 94 m/s. A curved section of the roadway is a circular arc of 740 m radius. The curved section is temporarily replaced with an unbanked roadway of the same radius.
 
  The coefficient of friction of this roadway is 0.40. The maximum safe driving speed for this unbanked, curved section is closest to: A) 54 m/s
  B) 52 m/s
  C) 50 m/s
  D) 48 m/s
  E) 46 m/s

Question 2

A car heading north collides at an intersection with a truck of the same mass as the car heading east. If they lock together and travel at 28 m/s at 46 north of east just after the collision,
 
  how fast was the car initially traveling? Assume that any other unbalanced forces are negligible.
  A) 40 m/s B) 80 m/s C) 30 m/s D) 20 m/s
