Pulleys and ropes are massless and frictionless. The coefficient of static friction between the mass m2 and the surface is µ(s) and the coefficient of kinetic friction is µ(k). The velocity of the mass m2 is V2 and the acceleration is a2. Give your answer in terms of (Ɵ, m1, m2, g, µ(s), µ(k) and V2). Under what conditions are V2 and a2 opposite direction. Hint: m1*a1=2*T-m1*g m2*a2=-T +/- cosƟ*m*g*µ(k) 2*x1=x2 => 2*a1=a2

Question
Pulleys and ropes are massless and frictionless. The coefficient of static friction between the mass m2 and the surface is µ(s) and the coefficient of kinetic friction is µ(k). The velocity of the mass m2 is V2 and the acceleration is a2. Give your answer in terms of (Ɵ, m1, m2, g, µ(s), µ(k) and V2).
Under what conditions are V2 and a2 opposite direction.
Hint:
m1*a1=2*T-m1*g
m2*a2=-T +/- cosƟ*m*g*µ(k)
2*x1=x2 => 2*a1=a2
