A 92-kg baseball player slides into second base as viewed in the picture (sliding to the left). The coefficient of friction between the player and the ground is µk = 0.61. What is the magnitude of the frictional force? What is the acceleration of the baseball player?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

i think the answer is a, hope this is right, that would be my best guess.

this could be newton#'s law of cooling. the cooling curve is exponential
