Question

find the resultant vector in terms of I cap and J cap component 10root 3meter 30°north of east,10meter due south​

Answer 1

Answer:

Explanation:

The first vector is 30° north of east.

Therefore its component along east direction (positive X axis) is

10√3cos 30 m/s=10√3 x √3/2=15 m/s

The other vector 10 m/s is due south which is considered the negative Y axis

Therefore

Along X Axis: 15 m/s

Along Y Axis: 10 m/s

Resultant : 15( i cap)+10( -j cap) = 15 i - 10 j (Ans)
