Hello, in this question we have three data tables.
00:04
Using this, we will find out the average acceleration, gravitation acceleration.
00:10
So let's start with the first one.
00:12
We have the height h1, which is equals to 0 .25 meter.
00:19
Then next, we can find out for the table one, the average time.
00:24
Average time for table 1.
00:30
So we can write it as a t1 which is equals to 0 .2193 plus 0 .2345 plus 0 .2437 plus 0 .2129 plus 0 .28 divided by we have total 5 values.
00:50
So we can write 5.
00:50
On simplification we will get 2288.
00:53
Divided by we have total 5 values.
00:56
So we can write 5.
00:57
On simplification we will get which is equal to 0 .227 second.
01:07
Now we can write the value of g1 which is equals to 2h divided by t square.
01:16
We will substitute all these values that is 2 multiplied by 0 .25 divided by 0 .227 square.
01:27
On simplification we will get the first answer that is 9 .25.
01:32
0703 meter per second square similarly we will find for second for the height h2 which is equals to 0 .37 and for that we have time average time t 2 which is equal to 0 .2698 plus 0 .2579 plus 0 .28 plus 0 .2855 plus 0 .29 plus 0 .276 divided by these 5 values, so divided by 5.
02:22
On simplification, we will get the answer of time t2, which is equals to 0 .6.
02:30
276 second...
