Rolling Ball IIA

See Rolling Ball I

A solid ball with a moment of inertia of I = 2 5 m r 2 I=\frac{2}{5}mr^2 is initially moving with a velocity of v i v_i and it is sliding with no rotational motion at t = 0 t=0 on flat ground (which you can assume to be extended to infinity).

The coefficient of kinetic friction is μ k \mu_k and coefficient of static friction is μ s > μ k \mu_s>\mu_k and are non-zero.

True or False?

The final velocity depends on the exact value of kinetic and static friction.

note: (assume the ball to be rigid and the ground too, so you don't have to consider rolling friction.)
