Abaseball has a mass of 0.140 kg, and it is pitched towards home plate at a speed of 52.0 m/s. assume that the ball is pitched horizontally and that the ball is hit horizontally back in the opposite direction. if the bat exerts an average force of 8900 n for 1.90 ms, what is the final speed of the ball in m/s?

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
