Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicatin

lyudmila [28]

Answer:

Following is the program in C language :

#include <stdio.h> // header file

#define n 5 // macro

int main() main function

{

int a[n],k1; // variable and array declaration

printf("Enter the element:\n");

for(k1=0;k1<n;++k1) //iterating the loop

{

scanf("%d",&a[k1]);//Read the values by user

}

printf("Output in Reverse Order:\n");

for(k1=n-1;k1>=0;--k1)//iterating the loop

{

printf(" %d ",a[k1]); //Display the values

}

return 0;

}

Output:

Enter the element:

Output in Reverse Order: 89 67 45 3 4

Explanation:

Following is the description of the program

Define a macro "n" with value 5 after the header file.

Declared an array "a" and defined the size of that array by macro i.e "n".

Read the value by the user by using scanf statement in the array "a"

Finally In the last for loop display the values of array "a" by space.

3.A ball is thrown into the air with an initial velocity of 15 m/s. a.How long does it take the ball to reach maximum height?b.W

ehidna [41]

Answer: a) = 1.5 sec. b= 11.5 m. c=0 d= 1.5 sec.

Explanation:

a) Once thrown into the air , the only influence on the ball is gravity, so, we can conclude that the acceleration acting on the ball is the one due to gravity, i.e., g= 9.8 m/sec².

Applying the definition of acceleration, we can write the following equation:

a= (vf-vo) / t ⇒ g = vf-vo / t. (1)

Now, when the ball reaches to his maximum height, it stops momentarily, and then starts to fall, so for this height, we can write vf=0.

Replacing in (1), and solving for t, we get:

t = (0 -vo) / g = -15 m/s/ - 9.8 m/sec² (Taking upward as positive direction)

a) t= 1.5 sec.

Replacing this value in the kinematic equation for displacement, when vo=15 m/s, we get:

hmax: 15 m/sec . 1.5 sec -1/2. 9.8 m/sec². (1.5 sec) ² (2)

b) hmax= 11.5 m

c) vf= 0 (as explained above)

Finally, in order to know how long the ball takes to return to its initial height, we know that for the falling part of the trajectory, vo=0, so we can write the equation for displacement as follows:

h=-hmax (because it returns to the same starting point)= 1/2 gt²=-11.5 m

Solving for t, we get:

d) t=1.5 sec.

It can be seen that the time used in going up, it is the same for going down, to travel the same distance.

This result is completely general and applies to any free fall problem.

Implement a program that requests the user to enter the x and y coordinates (each between 10 and 10) of a dart and computes whet

igomit [66]

Answer:

Following are the program in the Python Programming Language.

#import math package

from math import sqrt

#define function

def circle(x,y):

#return the square root

return sqrt( (x)**2 + (y)**2 )

#get input from the user

x = float(input("Enter first number between -10 and 10: "))

#get input from the user

y = float(input("Enter first number between -10 and 10: "))

#check condition

if(circle(x,y)<8):

#then, print message

print("It is in!")

#otherwise

else:

#print message

print("It is not in!")

<u>Output:</u>

Enter first number between -10 and 10: 1.5

Enter first number between -10 and 10: 2.6

It is in!

Explanation:

Here, in the following program in the Python Programming Language.

Define the function "circle" and pass the argument "x" and "y" then, return square root of x and y.

Set a variable "x" which get float type input from the user.
Set a variable "y" which get float type input from the user.
Set the if conditional statement to check that the function return the value less than 8 then, print the message.
Otherwise, it print the following message.
