Question

An object moves along the grid point Ab c d e and f are shown below the side of square tiles measure 0.5 km calculate the distance covered by the moving object

Answer 1

Answer:

2.5 km

Explanation:

SOLUTION :-

a) The distance covered by the moving object is calculated as follows:

AB + BC + CD + DE + EF

3 + 1 + 1.5 + 0.5 + 0.5 = 6.5 km

The distance covered by the moving object is 6.5 km.

b) The initial point is A and the final point is F, hence the magnitude of the displacement is equal to the distance AF which is calculated by applying Pythagora’s theorem to the triangle AHF as shown in the attachment.

Applying the Pythagorean formula, we get

AF²=AH²+HF²

Substituting the formula, we get

AF² = (0.5×4)² +(0.5×3)²

AF² = 6.25

AF = √6.25

.°. AF = 2.5 km.

The magnitude of displacement is 2.5 km.
