Hey Everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have this physics problem, and I'm not really sure how to solve it using linear and angular momentum, I know it can be solved otherwise in different methods, but I'm interested in this one..

The question is:

"A bowling ball is given an initial speed of 5 m/s on an alley such that it slides initially without rolling. The coefficient of friction between teh ball and the alley is 0.30. How far must the ball travel until pure rolling motion?"

Now I know that the friction force causes the change in linear momentum, and the change in angular momentum, so we equate them and solve using the formula of work..

But after I do that it gets really messy, and I had to add a negative sign for no reason to get the right answer..

So I would reeeally appreciate it if someone could write a full explanatory solution showing the steps, thanks a lot!
