A disk rotates at constant angular acceleration, from angularposition
u1 10.
0 rad to angular position
u2 70.
0 rad in
6.
00 s. Itsangular velocity at
u2 is
15.
0 rad/s.
a What was its angular velocityat
u1?
b What is the angular acceleration?
c At what angular positionwas the disk initially at rest?
d Graph u versus time t and angularspeed v versus t for the disk, from the beginning of the
motionlet t
0 then.
