One end of a string is fixed. It has over a pulley and has a block of mass 2.0 kg attached to the other end. The horizontal part has a length of 1.6 m and a mass of 20 g. What is the speed of a transverse pulse on the string?

Need help with all parts pls

44. A metal ramp 6.00 m long is tilted 10.0° and is used to load and unload a moving van. Suppose a 20.0 kg box is pushed up the ramp and it slides with a friction coefficient of 0.30. The ramp can be viewed as a “machine” where the useful output is the potential energy gain of the box and the input is the physical work done by the person doing the pushing. (a) Determine the efficiency of the ramp. (b) Determine the ratio of the force needed to lift the box without the ramp to the force needed to push it along the ramp (this is called the mechanical advantage).

The speed of a transverse wave on a string is 461 m/s, while the wavelength is 0.167 m. The amplitude of the wave is 1.93 mm. How much time is required for a particle of the string to move through a total distance of 1.28 km?

Transverse waves with a speed of 46.5 m/s are to be produced on a stretched string. A 5.40-m length of string with a total mass of 0.0600 kg is used. (a) What is the required tension in the string? (b) Calculate the wave speed in the string if the tension is 8.00 N. m/s

A sinusoidal wave is given by:  y= 8 sin (2x - 5t) cm determine the  transverse velocity vy of a point on this wave in cm/s at point x =8 cm for t=3 s.

A rope with a total mass of 25.0 kg is tied to a tree on one side of a 125-m wide ravine. You are pulling on the other end of the rope with a force of 415 N. If you pluck the rope at your end, how long will it take the pulse to travel across the ravine to the tree?

Two waves are traveling on the same string. The displacement of the first is given by y₁ = 0.0300 sin(400лt - 2лx) and of the second by y2 = 0.0300 sin (400лt - 2x + 44), with x and y in meters and t in seconds. What is the amplitude of the resultant wave? i m

A cable is stretched between two posts 3.00 m apart.The speed of waves on this cable is 96.0 m/s, and the tension in thecable is 175 N. If a standing wave on this cable has five antinodes, whatare the wavelength of the standing wave

A sinusoidal wave is traveling along a rope. The oscillator that generates the wave completes 37.0 vibrations in 33.0 s. A given crest of the wave travels 420 cm along the rope in 15.0 s. What is the wavelength of the wave?
