Can I also assume that the acceleration throughout the whole system is equal?

ok so I set up torque equations at different points starting from right to left of the diagram. starting at mass M1 1) T4-m1g=m1a At the pulley connected to M1 2)-T4(r) + T3 (r) = (1/2 Mr^2)(a/r) At the second pulley 3) -T2(r)+T1(r) = (1/2 Mr^2)(a/r) then at m2 T1-m2g = m2a Now The...

Homework Statement So I have this lab and I have no idea how to come about doing this. An Atwood machine consisting of two massless pulleys (one smart pulley without friction and one pulley with friction) and hanging masses will be provided, as shown in the diagram below. you will be given...

I get it, so at the point where vehicle 2 stops, that is when vehicle 1 is on the grass. Since the coefficient of friction of the grass is much lower, that is why he stops 5 feet after =D

Well I'm the friction is what stops the cars but I don't see how friction makes the other car go another 5 feet...

Or Maybe does inertia of after the two cars seperating make sense?

Homework Statement Explain why vehicle 1 traveled 5 ft further than vehicle 2 before coming to rest. Would you have expected it to come to rest at the same time as vehicle 2? Why or why not? Mass of vehicle 1 = 1406.13 kg mass of vehicle 2= 1950.45 kg Homework Equations Newtons third...
