Question 13 Tries remaining: 3 Marked out of 1.00 Flag question An object is acted on by two forces, X and Y. Force X acts vertically upwards with magnitude 16 N. Force Y acts horizontally from right to left with magnitude 31 N. Calculate the magnitude of the resultant force to the nearest newton and describe its direction in terms of the angle it makes with the horizontal, to the nearest degree. Magnitude of resultant force: N Direction of resultant force: from horizontal
