A 2.00-m-long rope has a mass of 0.100 kg. The tension is 55.0 N. An oscillator at one end sends a harmonic wave with an amplitude of 1.00 cm down the rope. The other end of the rope is terminated so all of the energy of the wave is absorbed and none is reflected. What is the frequency of the oscillator if the power transmitted is 120 W?
Relative to the ground, determine the angle of the velocity vector of the package just before impact.
A point source of light is 200 cm below the surface of a body of water. Find out the diameter of the circle at the surface through which light emerges from the water.

A ball is thrown upward at a speed v0 at an angle of 50.0° above the horizontal. It reaches a maximum height of 7.5 m. How high would this ball go if it were thrown straight upward at speed v0.

A fisherman reels in 12 of line while landing a fish, using the constant forward pull of 35. How much work does the tension in the line do on fish.
Light is incident from one medium with an index of refraction of 2.29 at an angle of 29.12 degrees with respect to the normal to the surface. The light then passes into another medium with a refractive index 1.44. With what angle is the light refr..
