A canister is released from a helicopter 500m above the ground. The canister is designed to withstand an impact speed of up to 1
Lisa [10]

Answer:

a) h = 1/2 gt² b) 99 m/s c) 14.1 m/s

Explanation:

a) As the only force acting on the canister once released is gravity, as it is constant, we can use one of the kinematic equations, as follows:

h = h₀ + v₀t + 1/2a t²

As we are told that the canister is simply released, it means that v₀ =0.

If we choose the direction of the acceleration (downward) as positive ,and we select the height at which it was released as our origin, so h₀ =0, the final expression for height is as follows:

h = 1/2 g t²

b) Combining this equation with the expression of t, from the definition of acceleration as the rate of change of velocity, we arrive to this expression:

vf² - v₀² = 2 g h  

As v₀ = 0, we have v₀ = √2.g.h = √2.9.8.500 m²/s² = 99 m/s

c) In order to be able to break the canister, impact speed must be larger than 100 m/s.

So, we can use the same equation as above, putting vf=100 m/s, and solving for v₀, as follows:

v₀² = vf² - 2.g.h = 100² m²/s² - 2.9.8.500 m²/s² = 200 m²/s²

v₀ = √200 m²/s² = 14.1 m/s

For any value of v₀ just barely larger than this, the canister will be broken.

Marrrta [24]

Answer:

// This program is written in C++

// Comments are used for explanatory purpose

#include<iostream>

using namespace std;

int main()

{

// Declare variables

int childticket, adultticket, childprice, adultprice;

double total, net, distributor;

string movie;

// Prompt user for name of movie

cout<<"Movie Name; ";

// Accept input for movie name

cin>>movie;

// Prompt user and accept input for price of adult tickets

cout<<"Adult Ticket Price: $";

cin>>adultprice;

// Prompt user and accept input for price of child tickets

cout<<"Child Ticket Price: $";

cin>>childprice;

// Prompt user and accept input for number of sold adult tickets

cout<<"Adult Ticket Sold: ";

cin>>adultticket;

// Prompt user and accept input for number of child tickets sold

cout<<"Child Ticket Sold: ";

cin>>childticket;

// Calculate total

total = childticket * childprice + adultticket * adultprice;

// Calculate distributor's payment

distributor = 0.25 * total;

// Calculate net box pay

net = 0.75 * total;

// Display and format results

cout<<"Gross Box Office Revenue: $";

printf("%.2f",total);

cout<<"\n Amount Paid to Distributor: -$";

printf("%.2f", distributor);

cout<<"\nNet Box Office Revenue: $";

printf("%.2f",net);

return 0;

}
