A vector has components Ax = 52.0 m and Ay = 41.0 m. Find: (a) The length of the vector A.
vredina [299]

Answer:

Part a)

A = 66.2 m

Part b)

Angle = 38.35 degree

Explanation:

Part a)

Length of the vector is the magnitude of the vector

here we know that

A_x = 52.0 m

A_y = 41.0 m

now we have

A = \sqrt{A_x^2 + A_y^2}

A = \sqrt{52^2 + 41^2}

A = 66.2 m

Part b)

Angle made by the vector is given as

tan\theta = \frac{A_y}{A_x}

tan\theta = \frac{41}{52}

\theta = 38.25 degree
