A wave traveling down a thin rope has a transverse displacement given byy(x,t) = (4.50 mm) cos(218 m-1 x +1550 s-1 t)
The rope has a length of 1.61 m and a mass of 0.00425 kg. Determine the following: (a) amplitude of the wave, (b) frequency of the wave, (c) wavelength of the wave, (d) wave speed, (e) direction the wave is traveling, (f) tension in the rope.
Mayan kings and many school sports teams are named for the puma, cougar, or mountain lion Felis concolor, the best jumper among animals. It can jump to a height of 11.6 ft when leaving the ground at an angle of 40.4°. With what speed, in SI units, do..
