Answer:

  • 0.03 m/sec

Step-by-step explanation:

Given

  • Θ= 168°
  • t = 0.28 sec
  • r = 3 mm

To find

  • Linear velocity

Solution

Formula for linear velocity

  • v = Θr/t

Converting the angle measure from degrees to radians

  • 168° = 168*π/180 = 168*3.14/180 = 2.93

Substituting values

  • v = 2.93*3/0.28 mm/sec =
  • 31.39 mm/sec =
  • 0.03 m/sec rounded to nearest hundredths
