(10%) Problem 10: A block with mass m1 = 7.9 kg rests on the surface of a horizontal table which has a coefficient of kinetic friction of .-0.67. A second block with a mass my-8.7 kg is connected to the first by an ideal pulley system such that the second block is hanging vertically. The second block is released and motion occurs. ied eted eted Otheexpertta.com write an expression for the sum of the forces in the y-direction S, fr block 2 20% Part (a) Using the variable T to re resent ens , Grade Sammary Potential 100% leted Atempts femaining 7 (1%per atiempt) detailed view 1 2 3 Hint Hints: 1-deaction per hint.

a) Fy = T - g*m2
b) Fx = T - µ*g*m1
c) a2 = a1
d) T = [g*m1*m2*(1+µ)]/(m1+m2)
e) T = 67.76 N
