# Rotational Kinematics

A solid ball with a diameter of 22 cm rolls along a horizontal surface as shown without slipping at a constant acceleration. It initially (t=0) has an angular velocity of 11 rad/s and 10 seconds later has an angular velocity of 3 rad/s.
(a)What is its angular acceleration? rad/s2
(b)What is the linear (translational) displacement of the ball? m
(c)How long (from t=0) will it take to stop? sec

15.4 m
and 13.75 seconds

Im so confused, can someone help me please????
