The angle %u03B8 through which a disk drive turns is given by %u03B8 ( t ) = a +

Question

The angle %u03B8 through which a disk drive turns is given by %u03B8(t)=a+bt%u2212ct3, where a,b and care constants, t is in seconds, and %u03B8 is in radians. When t=0,%u03B8=%u03C0/4rad and the angular velocity is 1.90rad/s , and when 1.80s , the angular acceleration is 1.20rad/s2

A-Find

a including their units.

B-Find

b including their units.

C-Find

c including their units.

D-What is the angular acceleration when

%u03B8=%u03C0/4rad?

E-What is

%u03B8 when the angular acceleration is 4.00rad/s2 ?

F-What is the angular velocity when the angular acceleration is 4.00

rad/s2 ?
