Question

The kinetic coefficient of friction between a body with mass ?1 = 8,00 ile and a surface on a slope ?1= 30.00 in a right triangular pattern given in the figure is 0.100. ?2 = 60.00 kinetic coefficient of friction between the mass of 2 = 7.00 moving on an inclined surface and the surface. The masses are tied together by a light rope passed through a frictionless reel as shown in the figure.
For a mass of m2 = 7.00 ?? to have an acceleration of 0.380 ?⁄?2,
a) What should be the tension in the rope because of the 7.00 ?? mass?
b) What should be ?? between the mass of 7.00 ?? and the surface?

(sin (30,00) = cos (60,0º) = 0,500 ; sin(60,0º) = cos(30,0º) = 0,866 ve g=9,80 m/s²)
m1 = 8,00 kg
m2 = 7,00 kg
\01 = 30,0°
02 = 60,0°(
