Question

The velocity of a free falling body just before hitting the ground is 9.8 ms, the height through which it fall
(A) 90m
(B) 19.6m
(D) 9.8m
(C) 4.9m​

Answer 1

Answer:

(C) 4.9m

Explanation:

Final velocity = v = 9.8 M/S

Acceleration =g= 9.8 m/s²

Initial velocity = 0

V=u+at

9. 8=0+9.8t

T=1 second

S=ut+½at²

S=1/2at²

S=½×9.8×1²

=4.9 m
