Explanation:

Average speed and average velocity both are different quantities.Speed is a scalar quantity but on the other hand velocity is a vector quantity.Speed deals with distance but on the other hand velocity deals with displacement and we know that displace is a vector quantity that is why velocity is a vector quantity.

$Average\ speed\ =\dfrac{Total\ distance}{Total\ time}$

$Average\ velocity\ =\dfrac{Total\ displacement}{Total\ time}$

If object is in uniform motion then speed and velocity will become same.

Both take the average speed.... however velocity also shows direction

anyanavicka [17]

Answer:

a. the magnitude of the force experienced by the muon is 2.55 × 10⁻¹⁹N

b. this force compare to the weight of the muon; the force is 1.38 × 10⁸ greater than muon

Explanation:

F= ma

v²=u² -2aS

(1.56 ✕ 10⁶)²=(2.40 ✕ 10⁶)²-2a(1220)

a=1.36×10⁹m/s²

recall

F=ma

F = 1.88 ✕ 10⁻²⁸ kg × 1.36×10⁹m/s²

F= 2.55 × 10⁻¹⁹N

the magnitude of the force experienced by the muon is 2.55 × 10⁻¹⁹N

b. this force compare to the weight of the muon

F/mg= 2.55 × 10⁻¹⁹/ (1.88 ✕ 10⁻²⁸ × 9.8)

= 1.38 × 10⁸

Calculate the average distances the car and the washer traveled from the top of the track. Record the averages and your qualitat

leva [86]

The distance the car traveled was 75 cm, and the distance the washer traveled was 200 cm. I know this because of coarse I had to calculate the distance and I just took the quiz and it said I got it right.
(I also calculated it again to make sure it was correct before I gave you the answer.)

P.S- Please mark me Brainliest, thank you (^v^).

Contact [7]

Answer:

138,516,546.9 horas.

Explanation:

Tenemos que usar la ecuación:

Velocidad = distancia/tiempo

Acá tenemos:

Velocidad = 0.3m/s

distancia = 149597870700 m

y queremos resolver la ecuación para el tiempo:

0.3m/s = 149597870700m/tiempo.

tiempo = 149597870700m/(0.3m/s) = 498,659,569,000 s

y sabemos que una hora tiene 3600 segundos, entonces si queremos transformar de segundos a horas tenemos:

498,659,569,000 s = (498,659,569,000/3600) h = 138,516,546.9 horas.

Explanation:

<u>Work and Kinetic Energy </u>

The work an object does due to its motion is equal to the change of its kinetic energy. Being ko and k1 the initial and final kinetic energy respectively and m the mass of the object, then

$W=\Delta k=k_1-k_0$
