Answer:
The magnitude = 10.30 m
The direction of the vector proceeds at angle of 119.05°
Explanation:
Given that:
A vector has component
= -5 m and
= 9 m
The magnitude of vector can be represented as:
=
=
=
=
= 10.30 m
If we make an angle
with y- axis:
Then; tan =
tan =
tan = 0.555
= tan⁻¹ (0.555)
= 29.05°
Angle with positive x-axis = 90 +
= 90° + 29.05°
= 119.05°
