floor at an initial velocity v0 = 6.00 m/s. The ball is not rotating initially, so w0 = 0. It

picks up rotation due to (kinetic) friction as it initially slips along the floor. The coefficient of

kinetic friction between the ball and the floor is μk. After a time ts, the ball stops slipping and makes a transition to rolling without slipping at angular speed ws and translational velocity _s. Thereafter, it rolls without slipping at constant velocity.

(b) Find an equation for the linear acceleration a of the ball during this time. The acceleration should be negative, since the ball is slowing down.

(c) Find an equation for the angular acceleration a of the ball while it is slipping. It will be

simpler if you use the sign convention that clockwise rotations are positive, so > 0.

(d) What constraint on w and v must take effect at time t = ts, the moment when the ball

stops slipping and begins rolling without slipping?

Here is my attempt:

b) slipping = rw + deltavt = vt

and then you get a derivative of it to get a = u_kg

c) a = torque / I

r(ru_kmg / 2/5mr^2) + dv/dt = -u_kg

and we get like -7/2u_kg from this...

d)....

please help!!
