There are two boxes with same mass couple together by a massless rope. One of the masses is on a ramp raised to an angle of 42 degrees, the other mass is hanging off to the right as shown in the figure. In between the two masses, the rope sun over a frictionless, massless pulley. If the mass on the ramp starts the problem at the top of the inclined plane, and the system is given a push, so that it is moving with an initial velocity pointing down the ramp. Ignore wind resistance for this problem. a) If the coefficient of friction is 0.30, what is the magnitude and direction of the acceleration of the system? Use the coordinate system given in the figure. (a=-2.71362 m/s^2 along the -x direction) What is the angle required for the the acceleration of the system to equal zero? Explain you reasoning with a few sentences.
