Question

(theta) = 168°; t = 0.28 sec; r = 3 mm. find its linear velocity.​

Answer 1

• 0.03 m/sec

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
