Answer:
90m
Explanation:
Distance is not a vector but a scalar quantity. depicted by a quantity only.
hence:
Distance is equal to 30+40+20 = 90 m
Explanation:
Below is an attachment containing the solution.
Susie's vertical displacement is 2.1 m
Explanation:
In order to solve this problem, we have to resolve the displacement vector along the vertical direction.
The vertical component of a vector is given by:

where
v is the magnitude of the vector
is the angle between the direction of the vector and the horizontal
Therefore, the vertical component of the displacement in this problem is given by

where
d = 3 m is the magnitude of the displacement
is the angle between the displacement and the horizontal
Substituting, we find
