Cannon Fire! Senior Physics Research Project

AI Thread Summary
The discussion focuses on a senior physics project involving a device that launches a cricket ball at an initial velocity of 28 m/s at a 30-degree angle. To determine the time it takes for the ball to reach its maximum height, the vertical velocity component must be calculated using the launch angle. This vertical component is then divided by the acceleration due to gravity to find the time. The calculations emphasize understanding projectile motion principles. The conversation highlights the application of physics concepts in a practical project.

Cannon Fire!

Can anyone please help me figre this one out;

A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launced at ground level with an initial velocity of 28m/s at an angle of 30 degrees to the horizontal. At what time will the ball reach its maximum height?

Figure the vertical velocity component from the angle.

Divide by the magnitude of gravity that is acting to slow it down.

That's your time.

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...
