Answer:

1. The magnitude of the vector is 26.9 m

2. The magnitude of direction of the vector is 21.8°.

Step-by-step explanation:

From the question given, we obtained the following data:

Displacement along x (Bₓ) = 25 m

Displacement along y (Bᵧ) = 10 m

Magnitude of displacement (B) =?

Magnitude of direction (θ) =.?

1. Determination of the magnitude of displacement of the vector (B)

Displacement along x (Bₓ) = 25 m

Displacement along y (Bᵧ) = 10 m

Magnitude of displacement (B) =?

B² = Bₓ² + Bᵧ²

B² = 25² + 10²

B² = 625 + 100

B² = 725

Take the square root of both side

B = √725

B = 26.9 m

Therefore, the magnitude of the vector is 26.9 m

2. Determination of the magnitude of the direction of the vector.

Displacement along x (Bₓ) = 25 m

Displacement along y (Bᵧ) = 10 m

Magnitude of direction (θ) =.?

The magnitude of direction of the vector can be obtained by using Tan ratio as illustrated below:

Adjacent = Bₓ = 25 m

Opposite = Bᵧ = 10 m

Magnitude of direction (θ) =.?

Tan θ = Opposite /Adjacent

Tan θ = Bᵧ / Bₓ

Tan θ = 10 /25

Tan θ = 0.4

Take the inverse of Tan

θ = Tan¯¹ (0.4)

θ = 21.8°

Therefore, the magnitude of direction of the vector is 21.8°.
