a flat plate of irregular shape has a mass of 4 slugs and a radius of gyration about the z axis of kg=.8ft the z axis passes through the plates center of mass G the plate is constrained to ratate about a second axis parallel to the z axis and .6 ft away from it. a moment of 20 lb ft is applied about the second axis, calculate the resulting angular velocity of the plate.
a -58nC charge is distributed uniformly along the x-axis from x = -1.3 m to x = 3.4 m. Consider a point at y = 2.2 m on the y-axis. a) what is the x-component of the electric field at the point
A rope connects a 25 kg mass sitting on a 30 degree incline with a hanging mass of 90 kg, the rope passes over a 12kg disk-shaped pulley that has a radius of 0.250m. When the system is released, the heavier mass descends, the rope turns over the p..
The output voltage of an AC generator is given by ?v = (120 V) sin (50?t). The generator is connected across a 25.0-? resistor. Find the power delivered to the resistor

A steel beam is placed vertically in the basement of a building to keep the floor above from sagging. Find the vertical compression of the beam
A metallic sphere initially has a charge of +8.60 nC. A negatively charged rod has a charge of -6.0 nC. What charge remains on the sphere after this transfer
An ocean liner leaves New York City and travels 21° north of east for 134km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions.
What are the two types of errors one encounters in experiments? Give an example of each, What does standard deviation of measured data tell you
An artillery shell of mass 10.00 kg, lying at rest on the ground, accidentally detonates, exploding into three pieces of shrapnel. find the angle at which the remaining piece of shrapnel travels
A freely falling object at Earth’s surface drops vertically 5 m in 1 s. Earth’s curvature “drops” 5 m for each 8-km tangent. Discuss how these two facts relate to the 8-km/s speed necessary to orbit Earth.
During an initial stage of construction, the beam is not to be bolted to the wall, but to be held in place solely by friction. What is the least coefficient of friction between the beam and the wall for the beam to remain in static equilibrium.
