When you put a book on a table the table pushes back. which newton law

6/12=1/2

step-by-step explanation:

the area between the graph and the t axis

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
