Answer:
26.67 s
Explanation:
v = Velocidad final = 40 m/s
u = Velocidad inicial = 20 m/s
= Tiempo inicial = 20 s
= Tiempo empleado durante la aceleración
a = Aceleración
s = Desplazamiento del automóvil durante la aceleración = 200 m
De las ecuaciones lineales de movimiento tenemos
El tiempo necesario para acelerar es 6.67 s
El tiempo total necesario para toda la ruta es 
.
Answer:
Explanation:
Consider downward displacement first .
downward displacement h = 38 m .
downward acceleration = g
downward initial velocity u = 0
h = ut + 1/2 g t ²
38 = 0 + 9.8 t ²
t = 1.97 s
During this period , there will be horizontal displacement with initial velocity u = 10 m /s and acceleration a = 1.6 m /s²
s = ut + 1/2 a t²
= 10 x 1.97 + .5 x 1.6 x 1.97²
= 19.7 + 3.10
= 22.8 m
Answer:
answer c. come easy dear.
Answer:
b. horizontal distance/time graph
Explanation:
d is incorrect because object is moving at the same pace the entire time
361 cubic meters of habitable space was available in the skylab. None of the given options are correct.
<h3>Who launched skylab?</h3>
NASA launched the first American space station, called Skylab.
The fuel tank of the Saturn SIV-B rocket stage served as the Skylab's residential quarters.
Skylab's livable capacity was large in comparison to the spacecraft that American astronauts had previously used 361 cubic meters.
Skylab offered 361 cubic meters of livable area.
Hence, none of the given options is correct.
