Civil engineers calculate suggested speeds around corners (those yellow signs) when designing roads based upon the ability of a car to remain upon the road. The ability of the car to remain upon the road when taking a corner is determined by the centripetal acceleration of your car around the corner. If you are driving a car around a flat circular turn with a suggested speed of 15 mph, how much more likely is it that your car does not successfully take the corner (ends up in the ditch) if you were to instead drive 45 mph? Cite an equation to back up your thinking.

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
