Alright Dude, If that worked for you... don't forget to give
THUMBS UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving down vote.
and, Thanks for using Chegg- Smarter way to study.
what are the units for torque, moment of inertia, and angular acceleration? show all work. write...
Match the units with the rotational quantity: Moment of inertia Angular acceleration Torque Rotational kinetic energy Angular Momentum a. kg·m2/s b. J c. N·m d. kg m2 e. rad s-2
Please write legibly and write out all equations and units. Please show all steps. Algebra-based physics only please. I struggle with manipulating equations and keeping angular and linear variables separate. We were unable to transcribe this image12. Two solid rods, each which length L, radius R, and mass M, are connected together, as shown. When they are rotated around the horizontal axis shown, what is the equation for the moment of inertia? Rotation Axis --- ----------- A {MR2 + 1ML?...
1. For a given torque, how does angular acceleration change if we double the moment of inertia of the object? 2. Mention at least two ways in which the moment of inertia of a cylindrical ring can be doubled.
Please write legibly and write out all equations and units. Please show all steps. Algebra-based physics only please. 5. An ice skater spins on the ice with her arms tight against her body. In this position, she has a moment of inertia of 1.2 kg.m² and an angular speed of 15 rad/s. She then stretches her arms out and her angular speed slows to 6.0 rad/s. What is her new moment of inertia? A B C D E 4.2 kg.m...
An object whose moment of inertia is 2.5·kg·m2 experiences the torque shown in the figure. What is the object's angular velocity at t = 2.4·s? Assume it starts from rest. 7 (Nm)
A flywheel has a moment of inertia of 0.015 kg m?. a How much torque do you need to create an angular acceleration of 3 rad/s“ ? b With this torque, what would the angular speed be after 6 seconds? C What would the angular momentum be after 6 seconds? d What would the kinetic energy of rotation be after 6 seconds?
PHY 221-Test 4 Problems: Show your work (diagrams, equations, mathematical manipulations, numerical substitutions, etc.) for all problems to receive credit (no work- no credit). Place a box around your final answer. Include units with all mumerical answers and record answers with the appropriate number of significant figures. All units must be in standard SI units. Include friction and/or air resistance only where indicated. 15) A grindstone has a moment of inertia of 1.6 x 103 kg-m2. When a constant torque...
