Kinematics Model Rocket problem

AI Thread Summary
A model rocket is launched with an initial speed of 49.6 m/s and accelerates at 1.83 m/s² until reaching an altitude of 155 m. To find the maximum height, the relevant kinematic equations must be applied, specifically v² = u² + 2a(s - s0) and v = u + at. The time to reach maximum height can be calculated using v = u + at, and the total time in the air can be determined with s = s0 + ut + 1/2at². Solving these equations will yield the maximum height, time to reach that height, and total flight duration. Understanding these kinematic principles is essential for solving the problem accurately.

Kinematics Model Rocket problem !

A) A model rocket is launched straight upward with an initial speed of 49.6 m/s. It accelerates with a constant upward acceleration of 1.83 m/s2 until its engines stop at an altitude of 155 m. What is the maximum height reached by the rocket?

B) How long after lift off does the rocket reach its maximum height?

C)How long is the rocket in the air?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
