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 I got -.8 rad/s^2 15.4 m and 13.75 seconds Im so confused, can someone help me please????
