The power of a truck engine is transmitted using the belt-and-pulley arrangement as shown in the figure. If the engine operates such that pulley C has a velocity of v_C = t² m/s, determine the velocity of pulley A after t = 10 s. Also determine the normal and tangential components of the acceleration of pulley A when t = 10 s.

1. What is the angular velocity of pulley C after 10 seconds?

2. what is the angular acceleration of pulley C after 10 seconds?

3. What is the angular acceleration of pulley B after 10 seconds?

4.What is the angular velocity of pulley A after 10 seconds?

5.Determine the magnitude of the velocity of pulley A when t = 10 s. Bepaal die grootte van die snelheid van katrol A wanneer t = 10 s.

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 .
