A rod of length L is hinged at one end. The moment of inertia as the rod rotates around that hinge is ML2/3. Suppose a 2.00-m rod with a mass of 3.00 kg is hinged at one end and is held in a horizontal position. The rod is released as the free end is allowed to fall. What is the angular acceleration as it is released?
A 66-N m torque acts on a wheel with a moment of inertia 175 kg m2. If the wheel starts from rest, explain how long will it take the wheel to make one revolution?
Blocks with masses of 2.0 kg , 3kg , and 6.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 53 N force applied to the 2kg block.
A 125 g wire is held under a tension of 218 N with one end at x = 0 and the other at x = 12.0 m. At time t = 0, pulse 1 is sent along the wire from the end at x = 12.0 m. At time t = 25.5 ms, pulse 2 is sent along the wire from the end at x = 0. A..
A grating has 776 lines per centimeter. Find out the angles of the first three principal maxima above the central fringe when this grating is illuminated with 603 nm light.
Calculate the amount Stansfield should report as net cash provided (used) by financing activities in its 2010 statement of cash flows. (Enter amount as positive.)
At what angle should the highway engineer bank. What is the magnitude of the acceleration.
A double speed trap is set up on a freeway. One police cruiser is hidden behind a billboard, and another is some distance away under a bridge. As a sedan passes by the first cruiser, its speed is measured to be 99.7 mph.
If the patch is 78 meters wide and the average force of air resistance on the skier is 179 newtons, explain how fast is she going after crossing the patch?
Consider the video tutorial you just watched. Suppose that we repeat the experiment, but this time we replace the original 56- magnet with a more powerful magnet of the same mass.
A student decides to move the box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 168 N at an angle of 30.0° above the horizontal. The box has a mass of 21.0 kg, and the coefficient of kinetic f..
A rigid tank contains 1.30 moles of an ideal gas. Determine the number of moles of gas that should be withdrawn from the tank to lower the pressure of the gas from 24.5 atm to 4.40 atm. Assume volume of the tank and the temperature of the gas rema..
Small telescopes are often advertised as "200 power" or "magnifies 200 times." As someone knowledgeable about astronomical telescopes, how would you progress such advertisements.
