A 500 gram mass oscillates with an amplitude 9.0cm and a frequency of 1.8 Hz. Determine its MAXIMUM speed and acceleration, and its speed when it is 4cm from its equilibrium position.
You have a 240- resistor and a 0.420-H inductor. Suppose you take the resistor and inductor and make a series circuit with a voltage source that has a voltage amplitude of 33.0 V, What is the voltage amplitude across the resistor
The rest energy E of an electron has a rest mass of 9.11 x 10 -31kg. Using Einstein's famous equation E = mc 2, find the rest energy of that electron
A fixed line charge +λ on the x-axis extends from x = d to x = 2d, and a fixed line charge -λ on the y-axis extends from y = d to y = 2d. Find the work required to bring a test point charge Q from infinity to the origin. Does the answer depend on the..
It collides with a 10,000 kg railway car resting at the bottom of the track with its brakes off. The two cars couple together and roll up the track to a height of h. find out h.
An 8.70-kg block slides with an initial speed of 1.56m/s up a ramp inclined at an angle of 27.4 degrees with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.62. Use energy conservation to find the distance the ..
