2 A sailboat on a lake sails 40. meters north and
then sails 40. meters due east. Compared to its
starting position, the new position of the sailboat
is
(1) 40. m due east (3) 57 m northeast
(2) 40. m due north (4) 80. m northeast

3

57m north east

Explanation:

Given that the boat sails 40. meters north and then sails 40. meters due east. The new position will be known by using pythagorean theorem.

P^2 = 40^2 + 40^2

P^2 = 1600 + 1600

P^2 = 3200

P = square root (3200)

P = 56.6 m

P = 57 m (approximately )

Therefore, the new position of the sail boat will be 57 north east

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
