Thanks for all the Help! I called one of my friends and he is going to explain it to me. Hopefully it will "click" We shall see. =]

Unfortunately, no numbers are provided in this problem. The only information given is what is written out above. and in general, yes. I know that the potential energy + kinetic energy of a system is constant as long as there aren't any nonconservative forces acting upon the object SumForces=...

Ok that would make sense. Could you help me set up the right side of the equation? I know that the block has an initial U energy of 0 and an initial K energy of 1/2mv^2. I don't know how to set up an equation for the block at the end of the ramp to find d. The only thing I know it that the m...

Homework Statement In the figure below, a block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial...

Homework Statement A 13 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 4.3 kN/m. The block is pulled to the right so that the spring is stretched 13 cm beyond its relaxed length, and the block is then released from rest. The frictional force between...

ha THANKS! As always, a retarded mistake.

Homework Statement Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber.If a sample of gold with a mass of 2.850 g is drawn out into a cylindrical fiber of radius 2.800 μm, what is the length (in m) of the...
