Vectors & scalars??A crane is lifting a girder up with a force of 3000 N. Two workers help to position the gir?

1.) Find the resultant force of the following 3 forces: 800 N toward the east; 600 N toward the west; 100 N vertically up

~223.6 N [east] at 26.6° with the horizontal

~423.9 N [east] at 116.6° with the horizontal

~223.6 N [west] at 26.6° with the horizontal

~302.5 N [west] at 153.4° with the horizontal

2.) https://d2l.cbe.ab.ca/content/cbel/math/cbel06sepm...

Possible answers:

~1374.8 N [38.7°] at 21.3° upward with the horizontal

~925.4 N [38.7°] at 21.3° downward with the horizontal

~572.6 N [60°] at 30° upward with the horizontal

~1374.8 N [21.3°] at 38.7° upward with the horizontal

3.) A plane travels with an airspeed of 500 km/h toward the north and climbs at an angle of 30° with the horizontal. A horizontal wind blows toward the west at 100 km/h. Find the resultant velocity of the plane.

~586 km/h [348.9°] at 29.5° to the horizontal

~124 km/h [48.1°] at 131.9° upward with the horizontal

~124 km/h [319.4°] at 39.8° downward the horizontal

~586 km/h [29.5°] at 348.9° to the horizontal

4.) A crane is lifting a girder up with a force of 3000 N. Two workers help to position the girder by pulling on ropes attached to the girder. One worker pulls with a force of 400 N east and the other worker pulls with a force of 500 N north. Find the resultant force that acts on the girder.

~7067.6 N [78°] at 38.7° with the horizontal

~3067.6 N [38.7°] at 78° with the horizontal

~3269.6 N [138°] at 29.1° with the horizontal

~7007.4 N [39°] at 78.4° upward with the horizontal
