Question

Two identical balls are released at the same time
from a building of height 85 m, one from the top
while the other from half way up,
Which of the following quantities is same for
both balls?
(a) Time of travel
(b) Final speed
(c) Acceleration
(d) Total displacement​

Answer 1

Answer:option 'a' is the answer

Explanation:because both the balls are same in everything so they will reach the ground at the same time.

Answer 2

Acceleration is same for both of them

That acceleration=g(gravitational acceleration)

Final velocity,v=√2gh

it is different for both because heights are different

Displacement is different because heights are different

Time =

$\sqrt{2h \div g}$

time is different because it depends on heights
