A bowling ball 26 cm in diameter is slid down an alley with which it has a coefficient of sliding friction of µ = 0.55. The ball has an initial velocity of 9 m/s and no rotation. g = 9.81 m/s2. Note: For a sphere Icm = (2/5)mr2.
a) What is the initial deceleration of the ball?
|a0| = m/s2
b) What is the initial angular acceleration of the ball?
|a0|= rad/s2
c) How long does it take before the ball starts to roll without slipping?
t = s
d) If it had been moving 13.5 m/s initially, how long would it have taken the ball to start rolling without slipping?
t' = s
