Physics
A small wooden block with mass 0.775 kg is suspended from the lower end of a light cord that is 1.62 m long. The block is initially at rest. A bullet with mass 0.0122 kg is fired at the block with a horizontal velocity v0. The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. When the block has risen a vertical height of 0.775 m, the tension in the cord is 4.82 N.
Required:
What was the initial speed v0 of the bullet?

Ответ:
No, the resulting wave in the diagram does not demonstrate destructive interference. The resulting wave in the diagram shows a bigger wave than Wave 1 or Wave 2. If it demonstrated destructive interference, it would be a smaller wave or a horizontal line. With destructive interference, waves break down to form a smaller wave, or cancel each other out, resulting in no wave formation.
