A rocket is launched from the ground and travels in a straight path. The angle of inclination of the rocket's path is 1.2 radians. (That is, the rocket's path and the ground form an angle with a measure of 1.2 radians.)]

Required:
a. What is the slope of the rocket's path?
b. If the rocket has traveled 85 yards horizontally since it was launched, how high is the rocket above the ground? _____yards.
c. At some point in time, the rocket is 313 yards above the ground. How far has the rocket horizontally (since it was launched) at this point in time? _____yards

Respuesta :

Answer:

a)[tex]S=2.57[/tex]

b)[tex]H=203.2yard[/tex]

c)[tex]X=121.79yards[/tex]

Step-by-step explanation:

From the question we are told that:

Angle [tex]\theta=1.2=68.755^o[/tex]

a)

Generally the equation for Slope is mathematically given by

 [tex]S=tan \theta[/tex]

 [tex]S=tan 68.755[/tex]

 [tex]S=2.57[/tex]

b)

Given the right Angle triangle with horizontal distance [tex]x=85yard[/tex]

Generally the equation for Height traveled is mathematically given by

 [tex]H=tan\theta*x[/tex]

 [tex]H=2.57*85[/tex]

 [tex]H=218.45[/tex]

 [tex]H=203.2yard[/tex]

c)

Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by

[tex]X=\frac{313}{tan65.75}[/tex]

[tex]X=\frac{313}{2.57}[/tex]

[tex]X=121.79yards[/tex]

Using the projectile principle, the slope of the rockets path, height above the ground and the distance traveled at a height of 313 yards would be 2.57, 218.63, 121.69 respectively.

Given the Parameters :

  • Angle of inclination = 1.2 radian

Converting to degree :

  • θ = 1.2 rads × 180/π = 68.755°

A.)

The slope of the rocket's path :

  • Slope = tanθ

Slope = tan(68.755) = 2.57

B.)

Horizontal distance, = distance along the x-axis = 85 yards

Vertical distance = height = distance along y-axis, y

  • y = tanθ × x

y = slope × x

y = tan(68.755) × 85

y = 218.63 yards

C.)

Vertical distance, y = 313 yards

From :

[tex] y = x tan\theta [/tex]

[tex] x = \frac{y}{tan\theta} [/tex]

[tex] x = \frac{313}{tan(68.755°)} [/tex]

x = 121.69 yards
