Calculated results Here it goes

I calculated those last questions I got them as X= -(wR)^2/8gb V of centre of mass as 0 since it come to halt And Ke total as 5M(wR)^2/32 are these correct ?

Yes initial rotation is related to linear speed as Initial speed =w_o*R/4

Actually this condition is already given in the text of the question and I have assumed it to be correct and calculated my answers based on that

And by halt I mean "When the object comes to a halt, all translational KE has been converted into heat. The frictional force Mg*b is constant throughout the sliding." Now I can see that it is definitely rolling with slipping / sliding

I am sorry then it is rolling with slipping And since "ANSWER TO B You then find w_t= -w_o + w_o/2= -w_o/2 Conclusion the disk is now standing still and it is rotating at half the angular velocity than at time t=0 but it is still rotating counter clockwise and thus it will roll back in the...

Thanks ! Yes it is rolling without slipping and spin axis is y (anticlockwise ) and translation direction is + x axis

A solid disk with mass M and radius R is moving at t=0 on a horizontal surface in the positive x-direction with speed w_o*R/4. The friction coefficient is b. At t=0 the disk is also spinning counter-clockwise with angular velocity w_o. Thus, when viewing the disk at time t=0 you will see it...
