A construction worker accidentally drops a brick from a high scaffold. What is the velocity (in m/s) of the brick after 8.0 s?

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

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.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
