Rotational motion (flywheel) problem

AI Thread Summary
To solve the problem of determining the energy required to travel 350 km while overcoming a frictional force of 450 N and accelerating from 0 to 95 km/h twenty times, one must consider the conversion of energy into rotational kinetic energy. The total energy needed includes work done against friction and the energy required for acceleration. The work done against friction can be calculated using the formula W = F × d, where F is the frictional force and d is the distance. Additionally, the kinetic energy for acceleration can be calculated using the formula KE = 0.5 × m × v^2, where m is mass and v is final velocity. The combined energy from both components will provide the total energy required for the journey.

The question is bascially asking how much energy is required to travel 350km, with a frictional force of 450N while acclerating from 0 to 95km/h twenty times. You know that all the energy will be 'stored' as rotational kinetic energy and will be converted to work done at the end of the trip.

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...
