B. 24 cm
C. 42 cm
D. 60cm

B. 57 cm
C. 9cm
D. -9 cm

B. 57 cm
C. 9cm
D. -9cm
Is it b?
4. In which of the following situations is the net displacement of an object equal to zero?
A. The object is moved -4 m in the x direction and 4m in the y direction
B. The object is moved -4 m in the x direction, -4 m in the y direction, and 4m in the x direction
C. The object is moved -4m in the y direction, 6 m in the y direction, and -2 m in the y direction
D. The object is moved -4 m in the x direction, 6 m in the x direction, and -3 m in the x direction
Is it c?
5. Travis travels 12 miles west and 22 miles south. What was his total distance?
Is it b?
6. What was Travis total displacement
A. 10 miles
B. 34 miles
C. -10 miles
D. 25 miles
Is it c?
1. D = 42-18 = 24 cm.
2. D = 9-18 = -9 cm.
3. 42-18 = 24 cm.
4. 6-4-2 = 0.
5. d = 12 + 22 = 34 Miles.
6. D = sqrt(12^2 + 22^2) = 25 miles.
1. To find the displacement of the caterpillar, subtract the initial position from the final position. In this case, the initial position is 18 cm and the final position is 42 cm. So, the displacement is 42 cm - 18 cm = 24 cm. Therefore, the answer is B. 24 cm.
2. To find the displacement of the caterpillar, subtract the initial position from the final position. In this case, the caterpillar moves from the 18 cm mark to the 42 cm mark, and then to the 9 cm mark. The initial position is 18 cm and the final position is 9 cm. So, the displacement is 9 cm - 18 cm = -9 cm (negative because the caterpillar moved in the opposite direction). Therefore, the answer is D. -9 cm.
3. To find the distance traveled by the caterpillar, add up the distances traveled in each segment. In this case, the caterpillar moves from the 18 cm mark to the 42 cm mark. The distance traveled in this segment is 42 cm - 18 cm = 24 cm. Therefore, the answer is A. 24 cm.
4. To find the net displacement of an object, add up the displacements in each direction. In this case, option C states that the object is moved in the y direction by -4 m, 6 m, and -2 m. Adding these displacements, -4 m + 6 m + (-2 m) = 0. Therefore, the answer is C. The net displacement is zero.
5. To find the total distance traveled, add up the distances traveled in each direction. In this case, Travis travels 12 miles west and 22 miles south. Adding these distances, 12 miles + 22 miles = 34 miles. Therefore, the answer is B. 34 miles.
6. To find the total displacement, subtract the initial position from the final position. In this case, Travis travels 12 miles west and 22 miles south. The west direction can be considered negative, while the south direction can be considered negative. So, the total displacement is -12 miles (west) - 22 miles (south) = -34 miles. Therefore, the answer is C. -10 miles.
