In the question we are given a vector like this.
00:05
This is the x -axis, this is the y -axis, and a vector l vector like this with making a 20 degree with the y -axis.
00:16
And we need to find the component of l vector along y -axis.
00:20
And in the question we are given l -vector's magnitude is equal to 8 .80 meter per second.
00:29
And the degree that is theta is equal to 20 degrees.
00:34
So, we know that if we have something like this, this is y -axis, this is x -axis, and let's say this is a vector v and this is theta, so v -y, that is equal to component of vector v along y -axis is equal to v -cos theta, and v -x, that is component of y -v vector along x -axis will be v -s -sign theta.

So, using the same concept, ly...
