Answer:

19.5 m

Explanation:

EN LANZAMIENTO DE PROYECTILES, LA VELOCIDAD HORIZONTAL

PERMANECE CONSTANTE.

PRIMERO ENCUENTRA LA VELOCIDAD VERTICAL

v^{2}y = 2(9.80 m/s^{2})(1.8 m) = \sqrt{35.3 m^{2}/s^{2}} = 5.94 m/s

LUEGO ENCUENTRAS EL TIEMPO QUE LA FLECHA PERMANECE EN EL

AIRE.

t =  5.94 m/s /9.80 m/s^{2} = 0.61 s

FINALMENTE ENCUENTRAS LA DISTANCIA HORIZONTAL TOTAL.

x = 32 m/s(0.61 s) = 19.5 m

What does a curved gradient line in a distance-time graph represent?
GREYUIT [131]

Answer:

If the line is curved, the slope is changing, which also means the velocity is changing. In a distance-time graph, the gradient of the line is equal to the speed of the object. The more the gradient (and the steeper the line) the faster the object is moving.

tankabanditka [31]

Answer:

Explanation:

5 C = 278 K

25 C = 298 K

V1 / T1 = V2 / T2

1.5L / 278 K = V2 / 298 K

V2 = (1.5L * 298) / 278

V2 = 1.61 L
