1. How much tension exists in each of two cables used to lower a 10m 500 kg gang plank to horizontal if the cables originate 2 meters above the planks hinges on the ship Relevant equations Moment of Inertia (Does it apply?) Torque Equilibrium (I'm so lost that I don't even know if torques...

for the energy of the wheel question i used KErot. 1/2*3024*(15700)^2 and got 3.726E11 Joules, does that seem right?

for the energy of the wheel I've calucated w and I, w=15700 rad/s and I=3024, but i don't get what to do next, no other information is given so I am wondering if its just an equation i need or what

i've been working on these today and I am getting closer, i worked out the first one for the second one what are they referring to when they say find the tension is that just the force required or what? for the third when they say electrical energy do they mean gravitational potential...

bump. sorry if that's not allowed

[b]1. Judy rides a 2m radius merry-go-round near its edge. Judy has a mass of 100 kg and the merry go round has a mass of 200 kg and rotates at 1 rad/s. What will the new angular velocity of the merry go round be if judy moves 45 percent of the way towards the center? 2.How much tension...
