Answer:

1.Solve for y in 2x+y=-3

y=-3-2x

2. Substitute y= -3 - 2x into 4x-2y=10

8x+6=10

3 Solve for x in 8x+6=10

x=1/2

4. Substitute x=1/2 into y = - 3 - 2x

y= -4

5. So you get...,

x=1/2

y=−4

Si un proyectil asciende verticalmente, y después de 3 segundos alcanza su altura máxima, calcule la velocidad que lleva a la mi

lys-0071 [83]

Answer:

The speed is 20.8 m/s

Step-by-step explanation:

If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory

Let the maximum height is h and initial velocity is u.

From first equation of motion

v = u + at

0 = u - g x 3

u = 3 g.....(1)

Use third equation of motion

$v^2 = u^2 - 2 gh \\\\0 = 9 g^2 - 2 gh \\\\h = 4.5 g$

Let the speed at half the height is v'.

$v^2 = u^2 + 2 gh \\\\v'^2 = 0 + 2 g\times 2.25 g\\\\v'^2 = 4.5\times 9.8\times9.8\\\\v' = 20.8 m/s$

Use the Sine Law: $\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$

In this case:
$\frac{sin(44)}{17}=\frac{sin(60)}{e}$
therefore:
$e=17\frac{sin(60)}{sin(44)} \approx 21.2$
