Answer:
D.) A 15 kg mass moving at 2.0 m/s
Explanation:
The inertia of an object is most directly related to its mass and not the magnitude of the velocity.
So, the higher the mass of an object, the more its inertia.
According to Newton's first law of motion "an object will remain in its state of rest or of constant motion unless it is acted upon by an external force".
- Inertia is the tendency of a body to remain in a state of rest either by virtue of its static position of constant motion.
- The larger the mass, the more this tendency.
- An object with a large mass will take more force to bring it from rest or change its motion.
Diffraction is the spreading of a wave from a gap.
The statements that are true about diffraction in the case above are;
<span>1. Both A and B will encounter waves. and
</span><span>6. Waves will reach A and B at the same time.</span>
I think its true, I think.
Given the final velocity (Vf) and the acceleration (a), the distance that should be traveled by the plane is calculated through the equation,
d = (Vf² - Vi²) / 2a
V1 should be zero because the light plane started the motion from rest. Substituting the given values,
d = ((33 m/s)² - 0)) / 2(3 m/s²)
The distance is therefore equal to 181.5 meters.
