Hi guys, now in this film, a mass of 2 .9 kz splits at the height of 0 .5 meter above the dotted line on the planar surface inclined at the angle of 30 degree.
00:12
Let me show you the diagram.
00:14
This is diagram.
00:15
Let me say this is what this is ground that i have.
00:18
And here we have an incline which is inclination is about 30 degree.
00:22
Our object is there which is at the height of what 0 .5 meter from the ground.
00:30
This is a object that i have here.
00:33
This is object i have where the height of this one is but only h is equal to 0 .5.
00:43
This is 0 .5 meter or i'll say 1 divided by 2 meter.
00:52
Inclination is but 30 degree.
00:55
A spring is there.
00:58
Here we have a spring.
00:59
This one will be looked like this.
01:07
Now when block is arrived at this position, it is speed is what v.
01:14
So we need to find out what is the largest compression in the spring now the largest compression in the spring will be when after a striding to the spring the velocity of block becomes zero and at that situation the compression in the spring will be larger in other words the total kinetic energy of the block is transferred to spring potential energy that is a position where the maximum compression will be happened but before that i need to find out this v when it arrive to this bottom of this plane.
01:52
So we get one this one is equal to 1 divide by 2 meter.
01:56
So this one will be what 1 meter.
01:59
This is 1 meter...
