Tuning Fork The end of a tuning fork moves in simple harmonic motion described by the equation d= asin(wt). If a tuning fork for the note E above middle C on an even tempered scale (E4) has a frequency of approximately329.63 hertz (cycles per second), find w. If the maximum displacement of the end of the tuning fork is 0.025 millimeter, determine the equation that describes the movement of the tuning fork.
A ball is thrown vertically upward with a speed of 1.63m/s from a point 4.21m above the ground. What is the time at which it will reach the ground.
A small block with mass m1 rests on a frictionless horizontal tabletop a distance r from a hole in the center of the table. A string tied to the small block passes down through the hole, and a larger block m2 is suspended from the free end of the ..
Two sinusoidal waves traveling in opposite directions interfere to produce a standing wave with the following wave function, Determine the wavelength of the interfering waves
A car in stop-and-go traffic starts at rest, moves forward 19 in 8.0 , then comes to rest again. The velocity-versus-time plot for this car is given in the figure. What distance does the car cover in the first 4.0 seconds of it motion?
A solid cube of mass 40kg and edge length .30mrests on a horizontal floor. A person then pushes on the upper edgeof the cube with a horizontal force of magnitude F. At what valueof F will the cube start to tip? Assume the frictional force fromthe flo..
Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2. Suppose that the blocks accelerate with an acceleration of magnitude a = 0.550 m/s^2 and that coefficient of kinetic friction b..
A 2.00 Kg wagon is pulled by a constant force of F= 72.0 Nat an angle θ = 60.0 on a level surface for a distance of 1.00m. There is no friction and the wagon is initially atrest.
A transformer is to be used to provide power for a computer disk drive that needs 6.6 V (rms) instead of the 120 V (rms) from the wall outlet. Find the number of turns in the secondary
