Charlie is driving down Kendall Drive. He drives 100 meters in 20 seconds. Assuming he does not speed up or slow down, what is his speed in meters per second? Formula: set up answer (with units)

c. newton's third law of motion

a.   mass number from atomic number

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.
