Write a computer program that computes the duration of a projectile’s flight and its height above the ground when it reaches the

target. As part of your solution, write and call a function that displays instructions to the program user. Note: Include functions in your program. Problem Constant G = 32.17 // gravitational constant Problem Inputs float theta // input - angle (radians) of elevation float distance // input - distance (ft) to target float velocity // input - projectile velocity (ft/sec) Problem Outputs float time // output - time (sec) of flight float height // output - height at impact

Answer:

#include <stdio.h> #define Gray 32.17 /* gravitational constant */ #include <math.h> /*cos definition*/ #define PI 3.14159265

int main(void) double Theta; /*input-angle(radians)of elevation*/ double Distance; /*input-distance (ft) to target */ double Velocity; /*input-projectile velocity (ft/sec)*/ double Time; /* output-time(sec) of flight*/ double Height; /*output-height at impact*/

printf("Enter Distance> "); scanf("%f", &Distance);

printf("Enter Radians> "); scanf("%f", &Theta);

printf("Enter Velocity> "); scanf("%f", &Velocity

Time = Distance / (Velocity * cos(Theta*PI/180.0) ) ;

Height = (Velocity *sin(Theta*PI/180.0)*Time) - Grav*(Time* Time) );

printf("The time of flight is %.3f seconds.\n", Time); printf("The height at impact is %.3f feets.\n", Height);

system("pause");

return (0);

a. Do you think the U.S. government should censor information on the Web, such as instructions for making weapons, to protect th
MrRissso [65]

Answer:

The answer is YES.

Explanation:

<em>Things pertaining to weapons, destructive materials should be shared with precautions or much better if these things should not be put online. Since internet is widely available to almost all types of users and almost to all places, we cannot be sure of who will get hold of these information. Kids could easily see this and gain knowledge and out of curiosity will try these dangerous things. Terrorist groups will also have access to these information and who knows might happen to poor innocent souls around.  </em>

<em> </em>

<em>I don't think it would violate the right of First Amendment regarding freedom of speech. Freedom should be granted on matters that are most sensible. And this time, we are just protecting the rights of children and other innocent people who can be a victim including you. We are talking about weapons and destructive materials here which is non beneficial if one could get hold of this information, in my opinion. If there is really a need to construct these things, it is better to consult an expert or an authority to ensure that nobody gets harm.</em>

How should you schedule a meeting with someone in another time zone?
gavmur [86]

If you know what timezone they're in, try to work out what time in your own timezone your free, then tell the other person to do the same. Tell them what times in your timezone and the other can search up what the time is in their own timezone. If there is a specific time when you are both free, use that.

Ex:

You live in the U.S. but you have a meeting with someone in the U.K. You're only free at 4:00pm-6:00pm and they're only free from 10:00am-11:00am. 11:00am in England is 4:00pm in the U.S. so do at that time!

Hope this helps!

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)​
alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

\dfrac{y-0}{x-4} = -4

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)
