The horizontal movement of the rocket is 11m/s, with an acceleration of 1.6m/s². The vertical movement will be downward, with an initial velocity of zero (it was shot horizontally) and a negative acceleration of g (-9.8m/s²)
To see how far the rocket traveled before hitting the ground, let's first figure out the time t at which the rocket hit the ground:
The formula for distance is d= vt + (1/2)at² ,
Where v=initial velocity, d=distance traveled, a=acceleration, and t=time
We want to find how long it took to travel 40 meters (height above the ground), given an initial velocity of 0 and negative acceleration of 9.8
Plugging into the equation:
40 = 0(t) + (1/2) (9.8) (t²) Multiply both sides by (2/9.8)
8.16 = t² Square root of both sides
t= 2.85
The rocket traveled for 2.85 seconds before hitting the ground. Plug this number into our distance formula to find horizontal distance
d= vt + (1/2)at²
d = 11 (2.85) + (1/2) (1.6) (2.85²)
Remember that initial horizonal velocity is 11m/s and horizontal acceleration is 1.6m/s²
Simplify:
d= 31.35 + .8 * 8.16
d = 37.87
The object traveled 37.87 meters before hitting the ground.
Answer:
Geocentric theory: Earth is the center of the universe.
Heliocentric theory: The Sun is the center of the universe.
Explanation:
The geocentric theory was formulated by Aristotle and says that the earth is the center of the universe and the other planets and stars including the sun revolve around it.
On the other hand, Copernicus with his heliocentric theory states that the sun is the center of the universe and the planets revolve around it.
They do not let electricity pass through their atoms, causing the electricity to be unable to move through the non metal
.
The answer would be A, since at that position the Earth is fully/partially being engulfed in a shadow cast by the moon from the sun’s rays.
Hope this helps!
Answer:
when your heart rate is not high than normal or lower than normally
Explanation:
Recovery heart rate is when your heart recovers from a certain heart rate eg high heart rate or even low heart rate this means you heart is now functioning normally .
