It is due to gravity. It is Earth's gravitation force that keeps our feet firmly on the ground.
You need the amount of time that it took to fall the 45m.
air resistance, on the moon they did an experiment where they dropped a hammer and a feather at the same height and time and they hit the ground at the same time
False, provided the drop occurs no sooner than the throw, and the ground is flat .
No. They both hit the ground at the same time, because the VERTICAL component of velocity in both cases is the same.
No. They both hit the ground at the same time. This is because the VERTICAL component of velocity in both cases is the same.

2s
Because they undergo an acceleration. Free fall velocity is the function of a square.
We all laugh
That is called gravity.
it is still hot but lying on the ground! :D

4 Seconds
4 seconds
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
False, provided the drop occurs no sooner than the throw, and the ground is flat .
