Car a is 16 kilometers to the west of car b. at noon, car a begins driving east at a constant speed 4 kilometers/hour, and car b begins driving north at a constant speed of 3 kilometers/hour. (a) (5 points) let x be the distance that car a has traveled since noon, and let y be the distance that car b has traveled since noon. let z be the distance between the two cars. find an equation that relates x to x and y.

The distance traveled can be found by kinematics equations

Explanation:

The initial position of Car B is denoted as origin. Car A started at -16 km, and moving right. Car B started at origin and moving up. z is the magnitude of the vector with components x and y.

The relation can be found by pythagorean theorem.

For checking the solution, we can find the positions at t = 4h. Car A is at the origin, and Car B is 12 km north of origin. z = 12.

magnityde and direction

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
