This law demonstrates that the energy within a close system may be converted from one form to another, but it cannot be created nor destroyed.

How do you find total displacement
Monica [59]

That's actually a lot easier than finding total <u><em>distance.</em></u>

To find displacement, you only have to know where the trip started from, and where it ended.   It doesn't matter what route was followed to actually travel from the start to the finish.  The displacement is the straight-line distance and direction between those two points.

Answer:

Therefore the terminal velocity = 1.45 m/s

Explanation:

Terminal velocity: Terminal velocity is the highest velocity of an object when it falls from rest trough a media.

V_t=\sqrt{\frac{2w}{c_d\rho A}}

V_t= terminal velocity

w = weight of the object = mg

c_d = drag coefficient=0.80

A= frontal area

\rho = media density = 1.2 kg/m³

m = mass = 8 kg

g= acceleration due to gravity = 9.8 m/s²

Front area = length× breadth

                 = (18×47)cm²

                 =846 cm²

Therefore the terminal velocity

v_t= \sqrt{\frac{2\times 87\times 9.8}{0.80\times 846 \times 1.2}

    =1.45 m/s

Therefore the terminal velocity = 1.45 m/s
