Answer:
counterclockwise
Step-by-step explanation:
= Small drive wheel radius = 2.2 cm
= Angular acceleration of the small drive wheel =
= Radius of pottery wheel = 28 cm
= Angular acceleration of pottery wheel
As the linear acceleration of the system is conserved we have
The angular acceleration of the pottery wheel is
.
The rubber drive wheel is rotating in clockwise direction so the pottery wheel will rotate counterclockwise.
= Initial angular velocity = 0
= Final angular velocity =
t = Time taken
From the kinematic equations of linear motion we have
The time it takes the pottery wheel to reach the required speed is
