Hello, here we have to find x and y components of three vectors.
00:05
First one is vector with a magnitude of 10 meters, which makes an angle of 30 degree clockwise with plus y axis.
00:18
So let's show it.
00:29
So therefore our x equals to r times sine of 30 degree, which is 10 meters times sign of 30 which is 5 meters and let's calculate our y that is r times cosine of 30 which is 10 meters times cosine of 30 degree that is 8 .7 meters now let's answer question b here velocity is has 25 meters per second magnitude and the it makes an angle of negative 40 degree counterclockwise from negative x.
01:17
It means that it is 40 degree clockwise from negative x.
01:33
Therefore, vx is negative v.
01:35
V .x is negative v.
01:37
Times cosine of 40 degree.
01:56
That is negative 19 .2 meters per second.
02:02
And let's calculate v .y.
02:04
3 times the sign of 40 degree...
