Question

If a dog moves 3 meters due East and then 4 meters due North, what will be the dispalcement of the dog?

Answer 1

5 m

Step-by-step explanation:

Displacement is the diatnce moves in a specified direction. It is the shortest distance covered by the dog. The displacement of the dog can be gotten by using the pythagoras theorem as shown;

According to the theorem, a²+b² = d² where d is the displacement

Substituting the given value into the fofrmula;

3²+4² = d²

9+16 = d²

d² = 25

square root both sides

√d² = √25

d = √25

d = 5 metres

Hence the displacement of the dog is 5metres
