m2, 8.5 kg, is accelerating down an incline at a constant rate. m1 is being pulled by a string attached between the two masses. The coefficient of friction between m1 and the horizontal surface is .22, the coefficient of friction between m2 and the incline is .38. The angle between the incline an the horizontal is 42 degrees. As a result the system accelerates down the incline at 1.65 m/s/s.
a) what is the mass of m1? 4.78 kg
b) what is the tension of the string connecting the masses? 18.2 N
I''ve included the answers, but could you show me how to get to them?
