When a fighter pilot makes a very quick turn, he experiences a centripetal acceleration. when this acceleration is greater than about 5.5 × g the pilot will usually lose consciousness ("black out"). consider a pilot flying at a speed of 890 m/s who wants to make a very sharp turn. what is the minimum radius of curvature that he can take without blacking out?

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

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.
