If a ball is dropped from rest, what is it’s velocity after 4 seconds

-39.2 m/s directed downwards

Explanation:

We can solve this problem with the following equation:

Where:

is the ball's velocity at 4 s

is the ball's intial velocity, since it was dropped from rest

is the acceleration due gravity, aways directed downwards

is the time

Solving:

Finally:

The negative sign indicates the velocity is downwards

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

the maxium height is 34m/s
