Answer to Question #11726 in C++ for temesgen

Question

the acceleration of a sleigh sliding down a hill is a=g sin (a), where a is the slope of the hill and the gravity acceleration g=9.8 m/s2.
a) write a c++ function that calculates the acceleration as a function of the slope a in degrees.
b)write a c++ program that reads the slope and length of the hill as inputs,and calculates how long time it takes to slide down the hill.

Answer 1

a) write a c++ function that calculates the acceleration as a function of the slope a in degrees.

double acc(double a){
return 9.8*sin(a);
}


b)write a c++ program that reads the slope and length of the hill as inputs, and calculates how long time it takes to slide down the hill.

# include<iostream.h>
# include<conio.h>
# include<math.h>

double a, l;

double time(double a, double l){
return sqrt(2*l/a);
}

void main(){
cout<<"Enter the length of the hill (in meters): ";
cin>>l;
cout<<"Enter the slope of the hill (in degrees): ";
cin>>a;
cout<<"It takes "<<time(a, l)<< " seconds to slide down the hill.\r\n";
getch();
}
