Answer:
Approximately
, assuming that the rocket had no propulsion onboard, and that air resistance on the rocket is negligible.
Explanation:
Initial velocity of this rocket:
.
When the rocket is at its maximum height, the velocity of the rocket would be equal to
. That is:
.
The acceleration of the rocket (because of gravity) is constantly downwards, with a value of
.
Let
denote the distance that the rocket travelled from the launch site to the place where it attained maximum height. The following equation would relate
to
,
, and
:
.
Apply this equation to find the value of
:
.
In other words, the maximum height that this rocket attained would be
.
Again, assume that the air resistance on this rocket is negligible. The rocket would return to the ground along the same path, and would cover a total distance of
.

Answer:
a) m = 59.63 [kg]
b) Wm = 95.41 [N]
Explanation:
El peso de un cuerpo se define como el producto de la masa por la aceleración gravitacional. DE esta manera tenemos:
W = m*g
Donde:
m = masa [kg]
g = gravedad = 9.81 [m/s^2]
m = W / g
m = 585 / 9.81
m = 59.63 [kg]
Es importante aclarar que la masa se conserva independientemente de la ubicación del cuerpo en el espacio.
Por ende su masa sera la misma en la luna.
El peso en la luna se calcula como Wm y es igual a:
Wm = 59.63 * 1.6 = 95.41 [N]
Answer:first law
Explanation:
it states the a body in motion or rest maintain its state until an external force is acted on it
To hit the target the crew drop the crate before the plane is directly over the target. It is because <span>because the cargo has forward velocity and therefore before it reaches the ground it travels some distance. The answer is A. Hope it helps. </span>
