Answer:
Dy = - 7.09 [m]
Step-by-step explanation:
In order to solve this problem, we must decompose the vector on the X & y axes using the angle with respect to the horizontal axis. Since this angle is negative the direction of the angle clockwise will be taken.
The Y component of the angle can be found using the sine function of the angle.
D = 9.55 [m], - 48°
Dy = - 9.55*sin(48) = - 7.09 [m]
