Question

Starting from the point of origin, a man walks 25 km in a direction below the +x-axis and then walks 30 km along the +y-axis to an endpoint. What is the displacement of the man from the starting point?

a) 55 km
b) 5 km
c) 30 km
d) 25 km

Answer 1

The displacement of the man from the starting point is 55 km.

Step-by-step explanation:

To find the displacement of the man, we need to find the total distance traveled in the x-direction and the total distance traveled in the y-direction.

The distance traveled in the x-direction is 25 km, which is below the +x-axis. Since the direction is below the +x-axis, it is negative.

The distance traveled in the y-direction is 30 km along the +y-axis. Since the direction is along the +y-axis, it is positive.

To find the displacement, we can add the distances together. 25 km (negative) + 30 km (positive) = 55 km.

Therefore, the displacement of the man from the starting point is 55 km.
