Question

A small wooden block with mass 0.700 kg is suspended from the lower end of a light cord that is 1.58 m long. the block is initially at rest. a bullet with mass 0.0108 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 4.90 n .

Answer 1

The question from the student pertains to the conservation of momentum in a collision and the resulting pendulum motion, which requires calculations based on principles of physics such as momentum conservation, energy conservation, and forces in pendulum systems.

Step-by-step explanation:

The question involves an understanding of conservation of momentum, energy transformations and tensions in pendulum systems, aspects commonly explored in high school physics. In scenarios where a bullet becomes embedded in a block and they together swing upwards as a pendulum, two primary conservation laws are considered: conservation of momentum to determine the velocity just after the collision, and conservation of energy to find out the height to which the block rises. Additionally, analyzing the tension when the block is in motion involves using the forces acting on the block at the peak of its swing. This includes the weight of the system and the centripetal force required for circular motion.
