Question

5. A Billiard Ball, radius 1.25 in and mass of 165 g , is released from rest and rolls down a smooth incline (like galileos ramp…) that is 8 ft long. The incline has a height of 4 in going to 0 inches in 8 ft. There I no slipping. The Q’s are…

a. How many revolutions did the ball make going down the incline?

b. What was the angular acceleration of the ball?

c. What was the tangential acceleration of the ball?

d. What’s the difference?

If you could clearly circle the answers I need that would be great!! Thanks!

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
