<u>Answer:</u>
Displacement = 100 meter
Distance covered = 180 meter.
<u>Explanation:</u>
Let east represents positive x- axis and north represent positive y - axis. Horizontal component is i and vertical component is j.
Carl runs 100 m West, Displacement = -100 i
He then runs 60 m North, Displacement = 60 j
He then runs 20 m East, Displacement = 20 i
Total displacement of Carl's running = -100 i + 60 j + 20 i = (-80 i + 60 j) m (Vector)
Magnitude of displacement = 
Distance traveled by Carl = 100 + 60 + 20 = 180 m ( Scalar)
Answer

force = 100 N
Point 37 degrees north of east
a) and b) part is shown in the diagram attached below.
c) to find the x and y component of the force
x- component of the force
y- component of the force
Answer:
the period of the 16 m pendulum is twice the period of the 4 m pendulum
Explanation:
Recall that the period (T) of a pendulum of length (L) is defined as:
where "g" is the local acceleration of gravity.
SInce both pendulums are at the same place, "g" is the same for both, and when we compare the two periods, we get:
therefore the period of the 16 m pendulum is twice the period of the 4 m pendulum.
I think the question meant to say net force on the box. Since force is a vector, the direction matters. 20N left is negated completely by the 50N right, which means the net force is 50N-20N to the right, 30N.
