Question

A body is moving from position coordinate(2,4) to position coordinate(3,5).Find its displacement vector.​

Answer 1

Given

• Initial position = (2,4)
• Final posting = (3,5)

To Find

• Displacement vector

Solution

☯ Displacement vector = Initial position - Final piston

• Here we would express the coordinates in the form of î + ĵ + k^

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

➞ Displacement vector = Final position - initial piston

• Initial = 2î + 4ĵ
• Final = 3î + 5ĵ

➞ Displacement = (3î+5ĵ) - (2î+4ĵ)

➞ Displacement = (3-2)î + (5-4)ĵ

➞ Displacement vector = î+ĵ

∴ The displacement vector is î+ĵ

Answer 2

Given information :-

A body is moving from position coordinate (2,4) to position coordinate (3,5). Find its displacement vector.

• Initial position = (2,4)
• Final position = (3,5)
• Displacement vector = ?

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━

Let's express initial and final position in form of î + ĵ + k^.

• Initial position = 2î + 4ĵ
• Final position = 3î + 5ĵ

Now, we have all required values so let's find its displacement vector. We clearly know that;

• Displacement vector = Final position - initial position

Putting all values we get,

➡ Displacement vector = (3î + 5ĵ) - (2î + 4ĵ)

➡ Displacement vector = 3î + 5ĵ - 2î - 4ĵ

➡ Displacement vector = 3î - 2î + 5ĵ - 4ĵ

➡ Displacement vector = (3 - 2)î + (5 - 4)ĵ

➡ Displacement vector = 1î + 1ĵ

➡ Displacement vector = î + ĵ
