Question

Can you do 35 A box of mass 2 kg slides along a encounters a spring with k - 500 N/m. 1 low far is the spring compressed when the box is A 0.45 meter long violin string is tuned to play at 440 Viz. What is the wavelength of the sound in centimeter? Assume sound velocity in air is 300 m/s. A rectangular door of length 1 meter is attached to a hinge on the ground. The door is raised degree, above the horizontal and dropped. What is its angular acceleration right after it is dropped? The moment of inertia (I) of the door is Mr^2/3.

Explanation / Answer

1) The spring is compressed at 0.19m when the box is brought to rest.

2) wavelength of sound is 0.68cm

3) the angular acceleration is a = 25.48rad/s^2
