Answer:

(a) 0.40 rad/s

(b) 0 m/s

Explanation:

Since the car is moving at a constant speed, the tangential acceleration of the car is 0 m/s.

To find its angular velocity, we use the equation ω = v/r.

Therefore, the angular velocity ω = 80/200 = 0.40 rad/s.

What's the difference between mechanical waves and vibrations
OlgaM077 [116]

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
