Question

A small wooden block with mass 0.725 kg is suspended from the lower end of a light cord that is 1.46 m long. the block is initially at rest. a bullet with mass 0.0114 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 0.800 m , the tension in the cord is 4.82 n .

Answer 1

The question is related to high school physics, focusing on the topics of momentum conservation during a bullet-block collision and the subsequent pendulum motion.

Step-by-step explanation:

The question pertains to the domain of Physics, more specifically to the topics of momentum, energy conservation, and dynamics. The motion described is a common example in high school physics courses, where students learn about the principles of collisions, conservation of energy, and simple harmonic motion.

The question involves a bullet embedding into a block and the resulting motion of the combined system, which can be analyzed using the conservation of momentum for the collision and subsequently the conservation of mechanical energy and dynamics (tension) of the combined system as a pendulum.
