A wire of uniform cross section weighing = 8 oz/ft is used to form the wire figure shown, which is suspended from cord AD. An impulse F ?t = (0.5 lb. s)j is applied to the wire figure at point E. Use computational software to calculate and plot immediately after the impact, for values of θ from 0 to 180°,
(a) the velocity of the mass center of the wire figure,
(b) the angular velocity of the figure.
Let east with the +x direction and north be the y+ direction. A driver travels 10 km east, 20 km north, and 50 km south west. Draw this path and the final displacement vector. Express the final displacement in components using unit vectors. What ..
A coil is placed in a magnetic field and has afflux FB through it. The coils stressed so that its area reduces to 55% of its original value. If the plane of the coil stays the similar and the flux through it remains the same, how should the magnetic ..
A vertical container with base area of length L and width W is being filled with identical pieces of candy,each with a volume of v and a mass m. Assume that the volume of the empty spaces between the candies is negligible.

In a certain RLC circuit, a46-? resistor, a11-mH inductor, and a 5-µF capacitor are connected in series with an AC power source for whichVrms=12V andf= 100 Hz.
A 40.0 kg box initially at rest is pushed 4.05 m along a rough, horizontal floor with a constant applied horizontal force of 145 N. find the work done by the applied force
A mass M is suspended from a spring and oscillates with a period of 0.860 s. Calculate the time it takes for the total energy of the oscillator to decrease to 0.50 of its initial value.
We have a typical student microscope with a rotating platform that allows the user to select from three objective lenses. calculate the highest and lowest magnitude of the overall angular magnifications available
A tabletop gamer has designed a game that requires three dice to be thrown onto a tray with a measurement grid. To add an extra degree of randomness, the coordinates of the center of mass of the three dice are used as well
