Answer:
Angular velocity: ()
Linear velocity: ()
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular (), in radians per second, and linear velocities (), in inches per second, of a point on the outer edge of the element are, respectively:
(1)
(2)
Where:
- Rotation rate, in revolutions per minute.
- Radius of the gear, in inches.
If we know that and , then the linear and angular velocities of the gear are, respectively:
()
()
First you need to combine like terms the get all numbers and leters to one side then divide to get g alone so your left with G=5
Answer is 9(-2)=-18 but that choice doesn't appear in your list of answers
%60 because i dont know why actually
40/120 = 0.33 repeating
or 33%
