Question

sarah jogs 2.5 km w and stops to rest. she then jogs 1.0 km w and stops at a neighbourhood park. whats her total displacement

Answer 1

Answer:

(2.5+ 1) km= 3.5 km

Explanation:

displacement is the shortest distance between initial and final position.

Sarah jogs 2.5km in West and again 1 km in West and she travel total 3.5km to reach the initial and final position.

so, displacement = 2.5 km +1 km= 3.5 km

Answer 2

Concept:

The displacement is the shortest distance between the object's initial position and its final position. Displacement is a vector quantity.

Distance is referred to as the length of a moving particle's real path. Distance is a scalar quantity.

Given:

Sarah jogs towards the west for 2.5 kilometers and stops. Then she jogs another 1.5 kilometers west.

Find:

Sarah's total displacement.

Solution:

Sarah jogs 2.5 kilometers west and then another 1 kilometer west then stop at a neighborhood park.

Displacement is defined as the shortest distance between the initial and final position of a body.

The total distance traveled by Sarah is 2.5 + 1.5 km = 3.5 km.

Therefore, Sarah's total displacement is 3.5 kilometers.
