Question

You walk for 1000 m northwards at a constant velocity of 3 m/s. Then you turn around, and walk with an average velocity of 0.5 m/s due south. From your starting point to your destination, your overall average velocity for the entire trip is 1.2 m/s due north. What is the northward total displacement during the entire trip?

Expert Solution

Step 1

Given,

Distance travelled in north direction is 1000 m at constant velocity of 3 m/s

d= 1000 m

u = 3 m/s

Then, it turn around and travel with average velocity of 0.5 m/s due south

Thus,

u₁ = 0.5 m/s

Total average velocity in north direction is,

V = 1.2 m/s
