A block of mass M=0.20 kg is attached to a spring with force constant k=12.0 N/cm. At time t=0, the mass is displaced from the equilibrium point by xi=6.0 cm and released with an initial velocity vi=5.0 m/s.
Calculate the period the resulting oscillations and the total energy of the system assuming no damping.
Determine the amplitude of the oscillations and the maximum speed of the block.
A person shoots a tennis ball out of a launcher. The tennis ball rises to a maximum height of 38 meters. a. What is the initial velocity of the tennis ball out of the launcher
At a grinding wheel has an angular velocity of 27. It has a constant angular acceleration of 26.0 until a circuit breaker trips at time = 1.60 . From then on, it turns through an angle 433 as it coasts to a stop at constant angular acceleration.
A 4.00 {rm A} current runs through a 12 gauge copper wire (diameter 2.05 {rm mm}) and through a light bulb. Copper has 8.5 times 10^ {28} free electrons per cubic meter.
A standing wave on a string is produced when one end is fixed and the other is driven by a 76 Hz oscillator, what is the total length of the string in meters
The plates of a parallel-plate capacitor in vacuum are 25 micrometer apart and 88 square cm in area, Calculate the charge on each plate, the capacitance and the energy density
You have a string with a mass of 0.0125 kg. You stretch the string with a force of 9.75 N, What is the wavelength of the standing wave you create in the string and What is the frequency
Anemometers (pictured) are used to measure wind speeds. Wind striking the cups causes the assembly to rotate; a gauge measures the frequency of this rotation and translates the data into wind speed. calculate the number of turns in the coil wire
