Calculate the resultant force if:
Sue push a box with a force of 7N to the right while John pull it 2N to the left.
Draw a vector diagram. Use vector addition to find the resultant vector. Determine the magnitude and direction of the resultant vector. Determine the magnitude and direction of the equilibrant vector.
Two boys try to move a heavy box. Both apply a force of 2N to the right on the box.

She stops for lunch and then drives 5 kilometres east.
What distance did she cover?
Distance = 7 + 5 = 12km
What was her displacement?
Displacement = √(x^2+y^2 ) = √(5^2+7^2 ) = √74 = 8.60km
θ= 〖tan〗^(-1) (opposite/adjacent)= 〖tan〗^(-1) (7/5)=54.46°
THUST 90o-54.46o = 35.54o
Anthony walks to the pizza place for lunch. He walks 1 km east, then 1 km south and then 1 km east again.
What distance did he cover?
Distance = 1 + 1 +1 = 3km
What was his displacement?
Displacement = √(x^2+y^2 ) = √(2^2+1^2 ) = √5 = 2.24km
θ= 〖tan〗^(-1) (opposite/adjacent)= 〖tan〗^(-1) (1/2)=26.57°
THUS 90o + 26.57 = 116.57o

On his fishing trip Justin and friends ride in a boat 12 km south. The fish aren’t biting so they go 4 km west. They then follow a school of fish 1 km north.
What distance did they cover? What was their displacement?
