Question

A man travels from house 200 m in 10 min due north and then 40 m in 10 min to due to east how much the velocity in the y-axis

Answer 1

Answer:

Here 10 m north means +y axis10j and 7m east means +x axis so 7i

displacement will be shortest path so 10 m and 7 m forms a right angle triangle whose hypotenuse is displacement

displacement=(10)2+(7)2=100+49=149≈12.2m
