Hello student, here we will first calculate the displacement of each of this step separately.
00:08
So here the displacement is s1, this is s2, here it's s3, this is s4, this is s5.
00:19
So s1 will be u1 t1 plus half f1 t1 square.
00:27
Now here u1 is 0, so 0 plus half into f1 is, here the acceleration for this is 2 .5 and time is 4.
00:42
So this is equals to, s1 equals to 20 meter.
00:48
Now similarly we can calculate f2 for this path.
00:53
For this path f2 is 0 minus 10 divided by 6 .5 meter per second square which is equals to minus 1 .5 meter per second square.
01:12
So s2 will be u2 t2 plus half into f2 t2 square.
01:21
So this is equals to 10 into 2 .5 minus half into 1 .5 into 2 .5 whole square.
01:32
So this is equals to 20 .32 meter.
01:40
Now for the next portion f3 is minus 5 minus 0 by 1 .5 meter per second square.
01:54
This is equals to minus 3 .33 meter per second square.
01:59
So s3 equals to u3 t3 plus half into f3 t3 square.
02:09
Now here we have u3 is 0, 0 minus half into 3 .33 into 1 .5 square.
02:24
So this is equals to minus 3 .74.
02:27
Now for s4 acceleration is 0...
