A proud deep-sea fishermen hangs an 61 kilogram fish from an ideal spring having negligible mass. The fish stretches the spring 0.130 meter.
(a) Estimate the force constant of the spring.
N/m
The fish is now pulled down 4.90 centimeter and released.
(b) Estimate the period of oscillation of the fish?
s
(c) Estimate the maximum speed it will reach?
m/s
At the time the switch is closed completing a simple LC circuit, the capacitor has 3.4 J of stored energy and the inductor has no stored energy. What is the energy stored in the inductor at that time

Kirk and Spock have the chance to take a tour of an ancient space station that was built before gravitational field generators were developed. Find the apparent acceleration experienced by the crew remaining on the rim
A pipe 0.0178 m in diameter and 0.16 m long can transfer 3726 J of heat per second with a temperature difference across the ends of 5?C. Compare this performance with the heat transfer of a solid silver bar of the same di- mensions by finding the rat..
Objects with masses of 100 kg and a 400 kg are separated with 0.340 m. Find the net gravitational force exerted by these objects on a 63.0 kg object placed midway among them. (Answer in Newton’s N)
On planet Tehar, the free-fall acceleration is the same as that on Earth, however there is also a strong downward electric field that is uniform close to the planet's surface. A 2.00 kg ball having a charge of 5.00 µC is thrown upward at a speed of 2..
Determine the enthalpy change and internal energy change of ammonia in J/mole, as it is heated from 350 K to 600 K, using the ideal gas heat capacity given by the Shomate Equation.
