a jet plane lands with a velocity of +100m/s and can accelerate at a maximum rate of -5.0m/s2 to0.00m/sits comes to rest can this plane land at an airport where the runway is 0.80km long ?

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
