1. An 80.0 kg box is pushed up a frictionless incline. Hypotenuse = 10.0 m. Opposite = 7.0 m. How much work is done on the box moving it to the top?

You need to show some attempt before anyone at PF can help you.

(Hint: Consider the change in potential energy of the box)
 
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...
