the answer is c because it is the 3rd step in the scientific analysis steps
You should include any source you used to obtain the information.
Answer:36.4 ft
Explanation:
Given
Span of Parabola
Maximum height
suppose Parabola is of type
where is the center of parabola
at
and it is given,
thus
at
First let us calculate for the angle of inclination using
the sin function,
sin θ = 1 m / 4 m
θ = 14.48°
Then we calculate the work done by the movers using the
formula:
W = Fnet * d
So we must calculate for the value of Fnet first. Fnet is
force due to weight minus the frictional force.
Fnet = m g sinθ – μ m g cosθ
Fnet = 1,500 sin14.48 – 0.2 * 1,500 * cos14.48
Fnet = 84.526 N
So the work exerted is equal to:
W = 84.526 N * 4 m

If there is equal tension on each side the rope won't move it would just get stretched out.<span />
