Given data is we have initial velocity, u is equal to initial velocity, u is equal to zero meter per second, final velocity v is equal to final velocity, v is equals to 15 meter per second, and s is equals to displacement is equal to we have 200 meter.
00:28
What we have to find is the acceleration and time.
00:32
We have to find acceleration a and time.
00:38
So we'll use the equation of motion over here.
00:40
And as we know from the second equation, and what we rearrange this, so it will be 2s is equals to v square minus u squared.
00:46
This is the third equation of motion, third equation of motion.
00:52
So we'll substitute all the values.
00:54
And here we get a is equals to v square minus u square upon 2s...
