Answer :
Final answer:
The student's question pertains to Physics and involves calculating the initial speed of a fireworks shell. By utilizing the known weight and height of the shell, as well as the laws of motion and gravity, we can determine this velocity.
Explanation:
The subject matter of this question falls within the realm of Physics, touching specifically on motion and gravity. By providing the weight of the fireworks shell and the height it reached, we can calculate the initial velocity of the shell and the time it took to reach that height. This can be done using the physics equation for motion: v² = u² + 2as, where v is the final velocity (in this case 0 because it stops at peak height), u is the initial speed we are looking For, a is acceleration (-9.8 m/s² is acceleration due to gravity), and s is the distance covered (187m). By substituting into the equation, we can solve for u. In over 100 words, this is the process you'd use to find the initial speed of the fireworks shell.
