If a ping pong ball and a basketnall were both dropped at the same time from the roof of our school ,which would hit the ground with a greater force ? common sense tells us that the basketball ball would. the difference in forces would be caused by the different masses of the balls . newton stated this relationship in his second law ,the force of an object is equal to its mass times its acceleration . what are two other situations where newton's 2nd law may apply ?

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.

Which is not true about oxygen-17 and oxygen-18?

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.
