Question

a body is released from height H above the ground which takes 30 seconds to reach the ground the position of the body after /t2 seconds is​

Answer 1

Answer:

14.7 meters

Step-by-step explanation:

For this we use the formula for nth second displacement that is

Sn + u + a(n-1/2)

Here, n is 2 and a is acceleration due to gravity i.e 9.8 m/s^2

So the value will be 9.8(2-0.5) which is 9.8 *1.5 which is 14.7.

Therefore the answer is 14.7 m.
