A new driver is speeding at 30m/s and sees the blue light of law enforcement in the distance and decides to slow down so he will not get a ticket. He taps the brakes and is soon going 25 m/s. If it took him 3s to do this what was his acceleration?

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
