Question

olivia places her pet frog on a line to observe the frogs motion. the line is divided into sections that measure 1 centimeter each. the frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backward, and then 12 centimeters backward. what is the frogs displacement? 0 6 18 36

Explanation:

Step1: Define forward and backward movements

Forward is positive, backward is negative. Initial position is 0. First move is +18 cm.

Step2: Account for second move

Second move is - 6 cm. New position is $0 + 18-6=12$ cm.

Step3: Account for third move

Third move is - 12 cm. Final position (displacement) is $12-12 = 0$ cm.

Answer:

0
