Explicación:
Para que podamos calcular el tiempo que le tomará al esquiador permanecer en el aire, encontraremos el tiempo de vuelo como se muestra;
T = 2Usin theta / 2
theta = 90 grados
U = 25 m / s
T = 25sin90 / 2 (9,8)
T = 25 / 19,62
T = 1,27 segundos
Por lo tanto, los cielos usarán 1.27 segundos en el aire.
La distancia horizontal es el rango;
Rango R = U√2H / g
R = 25√2 (80) /9,8
R = 25√160 / 9,8
R = 25 * √16,326
R = 25 * 4.04
R = 101,02 m
Por tanto, la distancia horizontal recorrida por el esquiador es 101,02 m
The soft underbelly of the axis is referred to as Italy. Hope this helps!
The masses of both objects and the distance between their centers.
The velocity of the car was 4.93m/s and the direction was northeast.
<h3>Calculation</h3>
It is given,
time of the trip = t = 3 minutes = 180 seconds
1st distance A = 1500ft = 457.2m east
2nd distance B = 2500ft = 762m north
We are asked to find the average velocity.
First, we get the resultant distance magnitude by applying Pythagoras theorem to find the hypotenuse.
![A^{2} + B^{2} =C^{2} \\C=\sqrt[]{A^{2} +B^{2} } \\C=\sqrt{457.2^{2} +762^{2} } \\C= 888.63m](https://tex.z-dn.net/?f=A%5E%7B2%7D%20%2B%20B%5E%7B2%7D%20%3DC%5E%7B2%7D%20%5C%5CC%3D%5Csqrt%5B%5D%7BA%5E%7B2%7D%20%2BB%5E%7B2%7D%20%7D%20%5C%5CC%3D%5Csqrt%7B457.2%5E%7B2%7D%20%2B762%5E%7B2%7D%20%7D%20%5C%5CC%3D%20%20888.63m)
Then we have
Velocity = Distance/time
Velocity = 888.63/180
Velocity = 4.93 m/s
Then the direction is northeast.
