The magnitude of the velocity vector of the car is ∣∣v→∣∣ = 78 ft/s. If the vector v→ forms an angle θ = 0.09 rad with the horiz

kotegsom [21]

Answer:

$\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$

Explanation:

The x- and y- components of the velocity vector can be written as following:

$\vec{v}_x = ||\vec{v}||\cos(\theta)\^i$

$\vec{v}_y = ||\vec{v}||\sin(\theta)\^j$

Since the angle θ and the magnitude of the velocity is given, the vector representation can be written as follows:

$\vec{v} = 78\cos(0.09)\^i + 78\sin(0.09)\^j\\\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$
