An airplane accelerates down a runway at 3.20m/s2 for 32.8s until it finally lifts off the ground. determine the distance traveled before takeoff.

from rest

dist = 1/2 accn timextime

=1/2 3.2 32.8x32.8

about 1.6x900 m/s ... 1350m

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.)
