A block of mass m rests on a 20 degree slope. The coefficients of static and kinetic friction are 0.80 and 0.50, respectively. The string is massless and the pulley is frictionless and massless.
(a) What is the minimum mass m that will stick and not slip?
(b) If m is the minimum mass found in part (a), it will start to slide after being given a little nudge. Determine its acceleration.
Thank you and I always have a problem with this class as far as the book but have gotten that straight and I do appreciate what you do. Thank you
You guys have provided me the best Technical Writing service. And that is in such a short time. Thank you so much.
Everything was amazing. I loved it because references used Perfect. I will continue working with you. Thanks
