A block of mass m1 = 3.5 kg sits on a rough, horizontal surface and is connected to a second mass m2 by a light string over a frictionless, massless pulley. The coefficient of kinetic friction between m1 and the surface is 0.41. If the acceleration of the system is 0.25m/s^2 predict the mass of m2

Answer 1

Net force= total mass * accelera
m2*g-.41M1*g=(m2+m1).25
solve for m2
