A student walks out of her science classroom and heads 15.0m (north) to the washroom.She leaves the washroom and heads 40m (south) to the math classroom. What is the students displacement from the science classroom to the math classroom?

Answer 1

To find the student's displacement from the science classroom to the math classroom, we need to find the net distance and direction from starting point to the ending point.

First, let's break down the student's movements:

1. She walks 15.0m north from the science classroom
2. She then walks 40m south from the washroom to the math classroom

The total distance covered is the sum of the two distances:
Total distance = 15.0m + 40m = 55.0m

Now, we need to find the direction of the displacement. Since the student initially moved north and then moved south, the net direction is south.
Therefore, the student's displacement from the science classroom to the math classroom is 55.0m south.
