In this problem, we're going to talk about uniform accelerated motion.
00:05
And in order to do that, we need to remember tertelli's equation.
00:08
So remember that if we have a particle that's undergoing uniform acceleration with an acceleration a, then it's speed squared is equal to the initial speed v0, plus two times the acceleration, times the distance between the initial position and the position when the speed is v.
00:28
So what we have, you know, a problem is a bush baby that's an african primate.
00:37
And he stretches his legs by a distance of 0 .16 meters from an initial velocity of zero.
00:47
That is initially the bush baby is at rest.
00:53
And in the process, he accelerates and reaches a final velocity view.
01:01
We don't know what v is, but all we know is that after he reaches this velocity, he jumps in the air, and the maximum height he reaches is 2 .3 meters.
01:14
And our goal is to find what is the acceleration a that the bush baby has during the jumping.
01:27
So first, notice that v0 is equal to zero.
01:30
This means that the final speed squared during the jumping, actually after the jumping, is equal to 2 times the acceleration times d.
01:45
Also, notice that this is the initial speed when he leaves the ground.
01:53
So this is v0 prime...
