You find angular acceleration? Maybe? That's the only correlation I keep finding. When I throw them in the T = I x α I get 90Nm / 0.01 = 9,000. Then I do 9,000 / 0.3s = 30,000 to try to get ωf but that seems huge and not correct.

I'm still pretty lost as someone who had a 66 on an exam for the Linear aspects. None of this has jived with me or my class in two months. It says the average torque is 90Nm, but I don't know what to do with that or where to put it. Most equations call for angles, but I can't even fathom of...

Is the 90degrees relevant to the equation? I looked over another, similar problem and then did this: T = 9kg x 33cm = 88.29N x 0.33m = 29.13Nm Then 29.13Nm / 0.03m = 971.19N But the other problem didn't have a value for degrees.

Homework Statement Lawrence is holding a 9kg dumbbell in his hand with his elbow flexed 90degrees. The horizontal distance from the center of mass of the dumbbell to the center of Lawrence's elbow is 33cm. The horizontal distance from the insertion of his elbow flexor tendons to his elbow is...

Homework Statement Stacy is throwing a discus. During the throw, she applies an average torque of 90Nm to the discus for 0.3 seconds. The discus has a mass of 1.0kg, and has a radius of gyration of 0.1m about its spin axis. If the initial angular velocity of the discus was zero, what was the...
