A mass of 4 kg goes down an incline at angle 27 degrees (see picture). Coefficient of kinetic friction of mass and incline is 0.195. A string with tension is on the mass and pulley (mass of 7 kg) with a radius of 0.11 m. The centre of the pulley rotates around a piece holding it in place. (ignore any static friction)
a) draw a free body diagram of this
b) find acceleration of the mass (m1)
c) Find angular acceleration of pulley
d) Find tension in the string
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
