Question

8. A car traveling down the highway moves at a speed of 68 mph going 15

degrees South of East. How far is the car moving in the Southern and
Eastern direction?

Answer 1

The car is moving 15 degrees South of East. This means that it is moving in a direction that is 75 degrees from the positive x-axis.

The velocity vector of the car can be broken down into its components in the x and y directions as follows:

vx = v * cos(theta) = 68 * cos(75) = 17.3 mph

vy = v * sin(theta) = 68 * sin(75) = 66.3 mph

where

v = 68 mph (magnitude of velocity)

theta = 75 degrees (angle of velocity vector with respect to the positive x-axis)

Therefore, the car is moving 17.3 mph in the Eastern direction and 66.3 mph in the Southern direction.
