Hello students, here is a caution and caution says a 10 kilogram ball is dropped from a height of 10 meter.
00:09
What is the given data? given is mass of the ball is equal to 10 kilogram from the height h is equal to the 10 meter.
00:21
Then what we have to find the kinetic energy just before it reaches the ground.
00:27
Okay, kinetic energy 8 point b, okay, we can say that is b.
00:35
This is the situation.
00:36
This is the ground and this is our building.
00:41
What is the height of this building? this is the 10 meter.
00:46
Okay, this is the 10 meter or we can say x.
00:49
The ball is fall down like this.
00:52
The initial velocity is equal to the zero.
00:54
When it reaches, this point, suppose this point is a and this point.
00:57
Is p and we have to find out the kinetic energy at point b.
01:00
Okay, when it reaches to the ground, okay, then we know that here is a here only conservative forces, only conservative forces, conservative force apply on it, apply on it...
