HI! I have a problem here about work and energy. !Help is needed!
"If a spring (on horizontal surface) is pressed down by 10N force the max. compress is 1m. What is the : a)Work done b)Potential energy gained by spring?"
First of all I found 10=k x 1 k=10N/m
Then work done...

A 1kg ball hits the wall with V= 5m/s and moves in opposite direction with V =4m/s. P1=5kgm/sec and P2=-4kgm/sec. But P1 must be equal to P2 from conservation of momentum , isn't that true...
Hi. I'm a newb here. I've got a problem about components of force. Water applies force to the walls of container as it does to the bottom. It has only horizontal compenent when the container is straight (walls parallel) but what about in containers with inward and outward sloping walls? In which...
