A wave is moving along a string. The equation giving the displacement y of a point at coordinate x and at time t has the form y = 0.2cos(4pi(x)/5-20pi(t)), where the units are in meters and seconds.
i.) Calculate the frequency and the speed(m/s) of the wave.
ii.) By reflecting this wave from a rigid support, standing transverse waves are set up on a stretched string. It is observed that the string is vibrating in its SECOND HARMONIC. Calculate the length of this string in meters.
An astronaut (mass of 100 kg, with equipment) is headed back to her space station at a speed of 0.750 m/s but at the wrong angle. What is her new direction (relative to the initial direction)
At a stop light, a truck of mass, mT = 1.10 x 10^4 kg, fails to hit its brakes until it has hit a car of mass,mC = 1.60 x 10^3 kg. Determine the velocity of the combined truck and car immediately after the collision
Two pipes of equal length are each open at one end. Each has the fundamental frequency of 500 Hz at 325 K. In one pipe the air temperature is increased to 330 K. If the two pipes are sounded together, what beat frequency results.
