Ahorse running at 11.5 m/s slows down to 6.50 m/s in a time of 2.5 seconds. what is the average acceleration of the horse? what is the average speed of the horse during this time interval

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
