Answer:

La magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

Explanation:

Podemos encontrar la velocidad con la que el martillo golpea el suelo usando la siguiente ecuación:

v_{f} = v_{0} - gt   (1)

En donde:

v_{f}: es la velocidad final =?

v_{0}: es la velocidad inicial = 0 (lo deja caer)

g: es la gravedad = 9.81 m/s²

t: es el tiempo = 9.5 s

Al reemplazar los valores anteriores en la ecuación (1), tenemos:

v_{f} = 0 - 9.81 m/s^{2}*9.5 s = -93.2 m/s                

El signo negativo se debe a que el vector velocidad está dirigido hacia abajo en el eje vertical (y).

Por lo tanto, la magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

Espero que te sea de utilidad!

Using the same cost and time estimates, consider any trade-offs that SciTech may have to make to complete the project.
ch4aika [34]

Answer:  

Oracio is the most cost-effective choice because he would cost the least to complete the project. However, he would also take the longest amount of time. Camilla could complete the job the fastest, but she costs more than Oracio. SciTech will have to decide if it is more important to save money or complete the work quickly to meet the deadline.  

Hope this helps :)

What is the speed of light? What is the speed of sound?
Rasek [7]

Answer:

speed of light simulating traveling at the speed of light. Speed of light, speed at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium

A body weighing 108N moves with speed of 5m/s in a horizontal
poizon [28]

Answer:

i) 5 m/s^{2}  ii) 54 N  iii) 54 N

Explanation:

i) a = \frac{v^{2}}{r} ⇒ a = 5² ÷ 5 = 5 m/s^{2}

ii) m = \frac{W}{g} ⇒ m = 108 ÷ 10 = 10.8 kg , F = ma ⇒ F = 10.8 × 5 = 54 N

iii) F1 = F2 = 54 N

50g of ice at 0°C is mixed with 50g of water at 80°C, what will be the final temperature of a mixture in
xxTIMURxx [149]

Answer:

0° C

Explanation:

Given that

Mass of ice, m = 50g

Mass of water, m(w) = 50g

Temperature of ice, T(i) = 0° C

Temperature of water, T(w) = 80° C

Also, it is known that

Specific heat of water, c = 1 cal/g/°C

Latent heat of ice, L(w) = 89 cal/g

Let us assume T to be the final temperature of mixture.

This makes the energy balance equation:

Heat gained by ice to change itself into water + heat gained by melted ice(water) to raise its temperature at T° C = heat lost by water to reach at T° C

m(i).L(i) + m(i).c(w)[T - 0] = m(w).c(w)[80 - T], on substituting, we have

50 * 80 + 50 * 1(T - 0) = 50 * 1(80 - T)

4000 + 50T = 4000 - 50T

0 = 100 T

T = 0° C

Thus, the final temperature is 0° C
