Rework your solution from the beginning and check each step carefully.
Two different simple harmonic oscillators have the same natural frequency (f=2.60 Hz) when they are on the surface of the Earth. what is the new frequency of the pendulum
At t = 0, the current through a 65.0 mH inductor is 52.0 mA and is increasing at the rate of 100 mA/s. What is the initial energy stored in the inductor
A hollow plastic sphere is held below the surface of a freshwater lake by a cord anchored to the bottom of the lake. find the buoyant force exerted by the water on the sphere
A 0.031 kg bullet is fired verticallyat 210 m/s into a 0.15 kg baseball that is initially at rest. How high does the combined bullet and baseball rise after the collision, assuming the bullet embedsit self in the ball?
A rigid body is assembled from 3 "mass-less" rods and three identical "point masses." The masses are placed separately at ai (i hat), aj (j hat), Find the inertia tensor for this rigid body
A transformer for an answering machine takes an acvoltage of amplitude 150 V as its inputand supplies a 7.9 V amplitude to the answering machine. The primary has 400turns.
Two capacitors are connected in parallel across the terminals of a battery. One has a capacitance of 2.06 F and the other a capacitance of 3.85 F. These two capacitors together store 5.28E-5 C of charge. What is the voltage of the battery?
A 416 kg car moving at 17.8 m/s hits from behind another car moving at 11.3 m/s in the same direction. If the second car has a mass of 757 kg and a new speed of 13.0 m/s, what is the velocity of the first car after the collision?
