Final answer:
The y-component of the vector is 9.39 m.
Step-by-step explanation:
To find the y-component of a vector, we need to multiply the magnitude of the vector by the sine of the angle it makes with the +x-axis. In this case, the vector has a magnitude of 12.1 m and makes an angle of 48.4° with the +x-axis.
So, the y-component is given by:
y-component = magnitude * sin(angle) = 12.1 m * sin(48.4°) = 9.39 m
