Two blocks with masses m¡= 3.00 kg and m2 = 4.00 kg are connected by a light piece of red string. The red string is draped over a frictionless pulley. Block m, is positioned on a rough ramp that makes an angle of 37.0° with the horizontal, while block m2 is positioned on a rough horizontal tabletop to the left of the ramp. The coefficient of kinetic friction between m¡ and the ramp is µ1= 0.250, and the coefficient of kinetic friction between m2 and the ramp is µ2= 0.100. Meanwhile, a third block of mass m3 = 0.0250 kg is connected to the other side of mass m2 with a piece of blue string. The blue string is draped over a second frictionless pulley so that mass m3 hangs vertically over the left side of the horizontal tabletop. When the system is released from rest, block m, travels down the ramp with an unknown acceleration a. Assume the strings connecting the blocks remain taut so that the whole system travels with the same acceleration. a=? a=? m2=4.00 kg Fri = ? a=? F72=? Hz = 0.100 m¡ = 3.00 kg Hj = 0.250 m3= 0.0250 kg 0= 37.0°
