Abowling bowl is thrown off the top of a building. determine distance the ball has fallen after falling for 3.0 s. remember, the gravitational acceleration (g) is 9.8 m/s2. (hint: d = ½gt2) a 3 kg lunch box is pushed across the lunch table. the acceleration of the lunch box is 2.0 m/s2. what was the net force applied to the lunch box? (hint: f = ma) show all your work! find the weight of a 10 kg rock. remember, acceleration due to gravity is -9.8 m/s2. (hint: w = mg) show all your work!

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.
