1. The problem statement, all variables and given/known data A block of mass m1 = 280 g is at rest on a plane that makes an angle θ = 30° above the horizontal. The coefficient of kinetic friction between the block and the plane is μk = 0.10. The block is attached to a second block of mass m2 = 220 g that hangs freely by a string that passes over a frictionless and massless pulley. Find its speed when the second block has fallen 30.0 cm. cm/s 2. The attempt at a solution Mass 1 Mass 2 Fground=280*9.81=2746.8 N Fm2 ground=220*9.81=2158.2 N Fgy=Fgcos(30) =433.714 N Fgx=Fgsin(30) =250.405 N Fkinetics=(.1)*(250.405) =25.04 N Fx= 250.405-25.04= 225.36N Fx=max 225.36=280*ax ax=.805 m/s2 It would be greatly appreciated if someone could please help! Thank you!
