Achild in a boat throws a 5.90-kg package out horizontally with a speed of 10.0 m/s. the mass of the child is 26.6 kg and the mass of the boat is 38.2 kg . calculate the velocity of the boat immediately after, assuming it was initially at rest.

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
