bad bro... jaja ill give it a shot and ill probably ask for more help later...ajaja

man, i don't see where this **** is going, I don't understand how KE will help me find Vf if there arent values for the variables

I understand that E=1/2 mv^2 +mgh, but i don't see how that gives you the velocity at half of the high when they don't mention mechanical energy

can you give the answer i really need this I am desperate!

i don't see how that is going to give me the answer for Vf

Homework Statement 13. A box of mass m is released from rest at point A, the top of a long, frictionless slide. Point A is at height H above the level of points B and C. Although the slide is frictionless, the horizontal surface from point B to point C is not. The coefficient of kinetic...

Homework Statement consider two positive charge+Q at the upper corners of a square. two negative charges-Q are located at the lower corners.assume that each side of the square is S. A) what is the total EPE of the array B)what is the electric field at the center of the square? C) how much...

when u say g you are talking about gravity right?

Homework Statement a skier starts from rest at the top of a 20° incline and skis in a straight line to the bottom of the slope, a distance D of 400 meters. if the coefficient of kinetic friction between the kis and the snow os .2, calculate the skier´s speed at the bottom of the run...
