The angle turned through by the flywheel of a generator during a time interval r is given by f=at+bt^(3)-ct^(4),where a, b, and care constants. What is the expression for its (a) angular speed and (b) angular acceleration?

The angle turned through by the flywheel of a generator during a time

1.	The angle turned through by the flywheel of a generator during a time interval r is given by f=at+bt^(3)-ct^(4),where a, b, and care constants. What is the expression for its (a) angular speed and (b) angular acceleration?
Answer» SOLUTION :(a)`a+3bt^(2)-4ct^(3)`, (B) `6bt-12ct^(2)`
