    Determine the magnitude of the torque

    No, that's what I meant. I hadn't noticed that it was cm instead of m! Thank you!

    Determine the magnitude of the torque

    Centimeters? Was it centimeters the whole time?

    Determine the magnitude of the torque

    Homework Statement A 25.0 N weight is held in the outstretched hand of a person with a shoulder-to-elbow length of 26.0 cm and an elbow-to-wrist length of 22.5 cm. The center of the weight is 7.5 cm from the person's wrist. A) Determine the magnitude of the torque about the elbow produced by...

    What is the Moment of Inertia of a Flywheel?

    Homework Statement The work done in accelerating a flywheel from rest to an angular speed of 14.5 revolutions per second is 22.0 kJ. What is the moment of inertia of the flywheel?Homework Equations ½Iω² = 22.0 kJThe Attempt at a Solution ½Iω² = 22.0 kJ I = (2)(22.0 kJ)/ω² ω = (14.5 revs/sec) =...

    Translational Speed of a Bowling Ball

    Oh my goodness, has this been my problem the whole time? I tried it, it was! You are such a lifesaver, thank you so much! I couldn't for the life of me figure out what I was doing wrong! Thanks again!

    Translational Speed of a Bowling Ball

    1. A bowling ball with a mass of 6.95 kg and a radius of 0.194 m starts from rest at a height of 2.21 m and rolls down a 49.2 degree slope. What is the translational speed of the ball when it leaves the incline? 2. Unsure! Here's what I've got, though: ω = v/r mgh=1/2mv2+1/2Iω2 And...
