What is the mass and direction of the third piece?

In summary, a small explosive charge placed in a rubber block on a frictionless surface causes the block to break into three pieces. The first two pieces, weighing 200g and 300g, travel at speeds of 1.4m/s and 0.90m/s respectively, with an angle of 80 degrees between them. The third piece has a mass and direction that can be calculated using two significant figures. A body diagram can be used to determine known values from the problem.

Homework Statement


A small explosive charge is placed in a rubber block resting on a smoother surface(frictionless). when the charge is detonated, the block
breaks into three pieces. A 200g piece travels 1.4 m/s and 300g piece travels at 0.90m/s. The third piece flies off at a speed of 1.8m/s.
If the angle between the first two pieces is 80(degrees), calculate the mass and the direction of the third piece. two sig figs.

First start is the body diagram. Indicate what you know from the problem.
 

1. What is the definition of "hard physics question"?

A "hard physics question" refers to a challenging or complex problem that requires a deep understanding of physics principles and concepts to solve.

2. What are some common examples of hard physics questions?

Examples of hard physics questions can include topics such as quantum mechanics, relativity, thermodynamics, and electromagnetism. Some specific examples may include calculating the trajectory of a projectile, understanding the behavior of light in a double-slit experiment, or explaining the concept of entropy.

3. How can I prepare for a hard physics question?

To prepare for a hard physics question, it is important to have a strong foundation in the fundamental principles of physics. This includes understanding mathematical equations and their applications, as well as developing critical thinking and problem-solving skills. Practice with various types of problems and seek help from teachers or tutors if needed.

4. Why are hard physics questions important?

Hard physics questions are important because they challenge our understanding of the physical world and push the boundaries of scientific knowledge. By attempting to solve these difficult problems, we can gain a deeper understanding of the laws and principles that govern the universe.

5. How can I approach a hard physics question if I am stuck?

If you are stuck on a hard physics question, try breaking it down into smaller, more manageable parts. Look for any given information or known values that can help guide your approach. Consider different perspectives and approaches, and don't be afraid to ask for help or seek additional resources.
