Aball whose mass is 0.4 kg hits the floor with a speed of 4 m/s and rebounds upward with a speed of 1 m/s. if the ball was in contact with the floor for 2.0 ms (2.0 × 10-3 s), what was the average magnitude of the force exerted on the ball by the floor? n calculate the magnitude of the gravitational force that the earth exerts on the ball: n

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
