hi there i have a question in which i can't get the answer i will show my work on what i did, if anybody can help , that would help alot .(adsbygoogle = window.adsbygoogle || []).push({});

here is the question:

only two forces act on an object (mass= 3kg)

x=40N

a=60N is at 45 degrees above the horizon

y= ?

find the magnitude and direction (relative to the x-axis) of the acceleration of the object?

i can use (a=60N)sin(45)= 42.42degrees, but where do i go from here, or whats the next step, i did try squaring y+x under the square root, but thats not the magnitude, because the answer in teh back of the book is different.

any help is welcome thanks
