i have assignment to submit on this monday.

i don't understand what the question is,can anyone help me?

**Projectile Motion**You will recall the tutorial problem in which you computed the height of a projectile

that was launched "straight up". In this case the height after

*t*seconds is given by:

2

2

Where

*uo*is the launch velocity in m/s and the gravitational constant

*g*is 9.8 m/s2.

In the simulation of the motion of the projectile the movement is monitored in very

short time intervals .

*t*. In a short time interval the velocity

*v*is almost constant and

the distance the projectile moves can be computed as

*.s*=

*v*.

*t*. The position can then

be updated by s = s + v * .

*t*;

The velocity changes constantly, it is reduced by the gravitational force. In a short

time interval,

*.v = -*g .

*t*, and the velocity must be updated as v = v – g * .

*t*;

In the new iteration the new velocity is used to update the distance.

However, most projectiles are not shot upright but at an angle to the horizontal. If the

starting velocity has magnitude

*v*and the starting angle of á, then the velocity is a

vector with components

*vx*=

*v*cos á,

*vy = v*sin á.

In the

*x*-direction the velocity does not change. In the

*y*-direction the gravitational

force has an effect. These equations presume there is no air resistance.

Write a program that will perform the simulation of a projectile that has been

launched with an initial velocity and angle. The user is to enter the initial velocity,

launch angle and the time interval.

The program will present the results in two formats. The user should be able to choose

which format to view.

1. Print the results in a table format on the screen, showing the height (

*y*position)

and range (

*x*position) at each time interval. Use the time interval to update the

position, but print out the position only every full second. Repeat until the

projectile has reached the ground level.

2. Plot the position of the projectile on the screen.

- Use a character display, similar to the sine wave example given earlier.

- The display should plot the x axis of the projectile on the horizontal

plane of the screen and y axis on the vertical plane of the screen.

- Hint: You could store the projectile position in a 2 dimensional array

that can represent the character positions on the screen. The contents of

the array can then be printed to the screen.

please help me.
