Angular Displacement, Velocity and Acceleration

If the translational velocity of an object is 3 m/s, and is located a distance of 2 m from the axis of rotation, what is the object's angular velocity?

• 0.67 rad/s
• 1.5 rad/s
• 5 rad/s
• 6 rad/s

A positive angular velocity indicates a _______ movement

• clockwise
• counterclockwise
• general
• good vibes
• accelerating

Angular velocity goes from -20 radians/sec to -12 radians/sec in 2 seconds. What's the angular acceleration?

• 8 rad/s/s (-)
• 8 rad/s/s (+)
• 4 rad/s/s (-)
• 4 rad/s/s (+)
• brain freeze

If angular velocity is clockwise and angular acceleration is counter-clockwise, the system is _______

• braking
• accelerating
• time travelling
• right hand rule
• All the above
