Writing a script for the Equation Of Motion

Hi,

I want to write a MATLAB script for the second equation of motion s=vo+1/2at^2. How would I approach this? Any help would be appreciated.

I am trying to simulate the trajectory of a bullet and I am finding it quite difficult as no values are assigned for conditions and therefore struggling as to where begin. Thank you

If you neglect friction from the air, then acceleration is g, 9.81 m/s, directed downwards.

V0 is the muzzle velocity; there is a whole Wikipedia article about muzzle velocities of various kinds of bullets. Pick one.

t is simulated time.

Thank you Walter !

Would Cos θ =vx/v

Sin θ =vy/v

be relevant within the MATLAB code if wanting to show horizontal distance travelled and maximum height achieved?

9.81 m/s^2

[Walter Roberson]

True, m/s^2

[Fergal Ahern]

Thanks for your help. What code would I use to read in the muzzle velocity and the launch value?

[Walter Roberson]

inputdlg() or just pass them as parameters to your function.

I suspect that you would be fine picking one particular common muzzle velocity such as for a 22 or a 303

Some examples of throwing. MAybe you can find them usefull for your bullet simulation
