In the figure, a slab of mass m1 = 21 kg rests on a frictionless floor, and a block of mass m2 = 9 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.30, and the coefficient of kinetic friction is 0.20. The block is pulled by a horizontal force of magnitude 58 N. What is the acceleration of the slab?

They don't really seem to have created a very good theory. They just seem to try and poke holes at evolution without providing evidence for an alternative theory. In fact they don't even have an alternative theory. What do you think?

And if the paint starts to run will the red run as fast as the yellow or will the grey rus as fast as the orange. Also if the sun is shining in the night will the day be darker than all the days in the past 100 years. Do you think this could happen if the moon is in the 2nd phase and it wont have the baby in the summertime???

two ellipses are drawn on the same graph, x^2/3 + y^2 = 1, and x^2 + y^2/3 = 1. How would I find the area contained within the two ellipses? ie. the area in the middle that both ellipses overlap on. I'm trying to use integrals and the area between curves, but i'm getting these ridiculously complicated integrals. Can anyone help? Thanks very much!
