    Final Initial
AI Thread Summary
To solve the high diver problem, the initial velocity and angle can be calculated using projectile motion equations, considering the height of the diving board and the time of flight. The maximum height reached above the water can be determined by analyzing the vertical motion and applying kinematic equations. The final velocity as the diver enters the water involves both horizontal and vertical components, which can be calculated using the time of descent and the initial velocity. The angle below the horizontal at which the diver strikes the water can be derived from the final velocity components. This approach emphasizes the importance of showing initial calculations and thought processes for effective assistance.

a high diver leaves the end of a 5.0 m high diving board and strikes the water 1.4 s later, 2.8m beyond the end of the board. Considering the diver as a particle, determine the following:
a) her initial velocity & angle above horizontal.
b) max height reached above water
c) final velocity as she enters the water & angle below the horizontal

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...
