Coefficient of friction for a rough incline is 0.50 . find the acceleration of a block down the incline of angle 2A where A is the angle of repose

6 years ago


Answers : (1)


u=tanA =0.5


  =g(2tanA-u(1-tan^2A))/1+tan^2A                          sin2A=2tanA/1+tan^2A

   a=g/2                                                                          cos2A=1-tan^2A/1+tan^2A

when we have a mass m on top of another mass M and we apply a force on the lower block (mass M) why is the the coefficient of static friction equal to that of coefficient friction?
simple reason: Due to Newton’s thord law of motion. that is: Every action has its equal and oppsoite reaction. Therfore that friction force acts on both blocks equal and opposite to each...
