A car is driving 20.7 m/s when the passenger throws a ball from the window at 3.7 m/s in the same direction as the motion of the car. Ignoring air resistance, what is the speed of the ball (in m/s)? (Assume both given values are to the nearest 10th).

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
