EastWind [94]

Answer:

1. $h = 244.8 m$

2. $x = 564.8 m$

Explanation:

1. La altura máxima se puede calcular usando la siguiente ecuación:

$v_{f}^{2} = v_{0}^{2} - 2gh$ (1)

Where:

$v_{f_{y}}$ : es la velocidad final = 0 (en la altura máxima)

$v_{0_{y}}$ : es la velocidad inicial horizontal en "y"

g: es la gravedad = 9.81 m/s²

h: es la altura máxima =?

La velocidad incial en "y" se puede calcular de la siguiente manera:

$tan(\theta) = \frac{v_{0_{y}}}{v_{0_{x}}}$

$v_{0_{y}} = tan(60)*40 m/s = 69.3 m/s$

Resolviendo la ecuación (1) para "h" tenemos:

$h = \frac{v_{0_{y}}^{2}}{2g} = \frac{(69.3 m/s)^{2}}{2*9.81 m/s^{2}} = 244.8 m$

2. Para calcular el alcance horizontal podemos usar la ecuación:

$x = v_{x}*t$

Primero debemos encontrar el tiempo cuando la altura es máxima ( $v_{f_{y}}$ = 0).

$v_{f_{y}} = v_{0_{y}} - gt$

$t = \frac{v_{0_{y}}}{g} = \frac{69.3 m/s}{9.81 m/s^{2}} = 7.06 s$

Ahora, como el tiempo de subida es el mismo que el tiempo de bajada, el tiempo máximo es:

$t_{m} = 2*7.06 s = 14.12 s$

Finalmente, el alcance horizontal es:

$x = 40 m/s*14.12 s = 564.8 m$

Jlenok [28]

Answer:

-30°C

Explanation:

F-32/180 =C-0/100

or, -22-32/180=C/100

or, -54/180*100=C

or, -0.3*100=C

therefore, C= -30

-22°F = -30°C

Brut [27]

Answer:

reliability

accuracy

Explanation:

If a reading of a measurement is consistently the same then the measurement is reliable.

If a reading of measurement is close the actual value of the measurement then the reading is accurate.

Here, a stationary tree shows reading 6 mph once and 0 mph another instant. So, neither the reading of a measurement is consistent not the reading of measurement is close the actual value.

Hence, the radar has problems in its reliability and accuracy
