A wheel with a radius of 1 meter is initially spinning with an angular velocity of 10 rotations per minute. A break is applied to the edge of the wheel which causes it to slow the rate of its spin with constant acceleration. a. If the rate of angular acceleration is -5 rad/s, how many seconds pass between the time the break is applied, and the wheel turns another 720 degrees? b. At that same instant (when the wheel with the break applied has just turned 720 degrees), what is the centripetal (radial) acceleration of a point on the edge of the wheel?

Question
A wheel with a radius of 1 meter is initially spinning with an angular velocity of 10 rotations per
minute. A break is applied to the edge of the wheel which causes it to slow the rate of its spin
with constant acceleration.
a. If the rate of angular acceleration is -5 rad/s², how many seconds pass between the time the
break is applied, and the wheel turns another 720 degrees?
b. At that same instant (when the wheel with the break applied has just turned 720 degrees), what
is the centripetal (radial) acceleration of a point on the edge of the wheel?
