Answer:
v=14.14 m/s
t=1.141 s
Explanation:
Given that
h = 10 m
Initial velocity ,u = 0 m/s
We know that acceleration due to gravity g= 10 m/s²
Lets take final velocity = v
Final velocity v is given as
v² = u²+ 2 g h
v²= 0² + 2 x 10 x 10
v²= 200
v=14.14 m/s
Time taken t is given as
v= u + a t
a=acceleration
t=time
Now by putting the values in the above equation we get
14.14= 0 + 10 x t
14.14 = 10 t
t=1.141 s
