Olivia places her pet frog on a line to observe the frog motion. The line is divided into sections that measure 1 centimeter each. the frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backwards, and then 12 centimeters backward. What is the frog's displacement?

Respuesta :

There is no displacement. The frog is back where it began.

Answer:

displacement of frog is zero

Explanation:

Displacement of the frog is given as

[tex]d_1 [/tex] = 18 cm forward

[tex]d_2 [/tex] = 6 cm backwards

[tex]d_3 [/tex] = 12 cm backwards

so here we have

[tex]d_1 = 18 cm[/tex]

[tex]d_2 = -6 cm[/tex]

[tex]d_3 = -12 cm[/tex]

so we have

[tex]d = d_1 + d_2 + d_3[/tex]

[tex]d = 18 - 6 - 12[/tex]

[tex]d = 0[/tex]
