A 15-kg car is placed on a track. The car carries a charge of +0.001 C. The car is initially located 60 m to the right of point A moving to the left with a velocity of 10 m/s. A fixed positive charge of +0.002 C is located at point A. Determine the speed of the car when it reaches point B, located 20 m to the right of point A.
