Velocity, unlike speed, includes a direction.
Velocity is a vector quantity which is defined by magnitude and direction.
Speed is a scalar quantity. It is the rate at which an object moves regardless of which direction.
You can use the impulse momentum theorem and just subtract the two momenta.
P1 - P2 = (16-1.2)(11.5e4)=1702000Ns
If you first worked out the force and integrated it over time the result is the same
Answer:
1.9 m.
Explanation:
Three complete waves in the length of 5.7 m
The distance traveled by one complete wave is called wavelength.
Thus, the distance traveled by one wave = 5.7 / 3 = 1.9 m
Thus, the wavelength is 1.9 m.
REALISM shows things as they REALLY look.
Answer:
The law of reflection (in physics) states that when a light ray is incident on a plane surface, the incident ray, the reflected ray and the “normal” to the surface of the mirror all lie in the same plane. It also states that the angle the incident ray makes with the normal is equal to the angle that the reflected ray makes with the normal.
