A 58.6g mass connected to a spring with a force constant of 31.2 N/m oscillates on a horizontal, frictionless surface with an amplitude of 3.70 cm.
(a) Calculate the total energy of the system.
(b) Calculate the speed of the mass when the displacement is 1.16 cm.
(c) Calculate the kinetic energy when the displacement is 2.50 cm.
(d) Calculate the potential energy when the displacement is 2.50 cm.
In the Millikan oil-drop experiment, an atomizer (a sprayer with a fine nozzle) is used to introduce many tiny droplets of oil between two oppositely charged parallel metal plates.
An antitank weapon fires a 4kg rocket which acquires a speed of 50.0 m/s after travelling 90 cm down a launching tube. Assume the rocket was accelerated uniformly, what is the average force acted on it.
We have pumped 20 bbls of fluid from the cement unit. But we think that we should have already achieved 425 psi at the unit. We are rigged up to do F.I.T and have already pressure tested all surface lines and there are no leaks.
Light with wavelength 595nm is incident on a 2.6?m wide slit. Find the angular width of the central peak in the diffraction pattern
In the Bohr model of the hydrogen atom, an electron in the 7th excited state moves at a speed of 4.47 104 m/s in a circular path having a radius of 2.59 10-9 m
The units can either be sold at the split-off point for $9 each, or processed further at total cost of $9,500 and then sold for $12 each. Illustrate should product X be processed further or sold at the split-off point?
You throw a bouncy ball directly down toward the ground. When it leaves your hand, 1 m above the ground, it is moving at 5 m/s. What is the ball's maximum height after it bounces
The magnetic flux that passes through one turn of a 18-turn coil of wire changes to 5.0 Wb from 14.0 Wb in a time of 0.020 s. What is the resistance of the wire
How does the magnitude of electrical force between a pair of charged objects change while the objects are moved twice as far apart? Three times as far apart.
What is the maximum speed of the ball.
a man is standing near a gate and a flag pole. The gate is 15 ft from the pole. If the pole is h=35 ft tall, how far is the man from the gate
