An object is dropped from a height of 50 meters. ignoring air resistance, how long doe take to hit the ground?

here given that object is dropped from height h = 50 m

So here we can say

initial speed is ZERO

acceleration is due to gravity

now in order to find time to reach the ground we can use kinematics

now plug in all values in it

so it will take 3.2 s to reach the ground

massxgravity x heght=weightxheight= pe

4900=490xh

h=10
