Explanation / Answer
Let horizontal axis be x and vertical be y
write F1 in vector form:
F1 = 4.90 cos 34.0 i + 4.90 sin 34.0 j
F1 = 4.06 i + 2.74 j
write F2 in vector form:
F2 = 5.00 j
add both vectors:
F1 + F2 = 4.06 i + 2.74 j + 5.00 j
= 4.06 i + 7.74 j
magnitude = sqrt (4.06^2 + 7.74^2)
= 8.74 unit
direction = atan (y component / x component)
= atan (7.74 / 4.06)
= 62.3 degree counterclockwise from the +x axis
