I went to ask my teacher for extra help and we were doing a problem about an object sliding down a ramp. When I calculated the Fnet I added all the forces together acting on the box but she said that you only take into account the horizontal forces. Any clarification would be much appreciated!
Hi all, I just registered for this forum and I am excited to learn a lot! I am taking physics this year and I am enjoying it a lot although it is quite difficult for me.
how do I calculate μ sub s and μ sub k(formulas would be excellent)?
