    Undergrad Speed loss per second due to air resistance

    Thank you for your help. Also by incorrect units it should be 113m/s2 ?

    Undergrad Speed loss per second due to air resistance

    I drew it and I think I get it now. Drag force is 408N. Using force formula (a=f/m), force = 408N, mass = 3.6kg, the deceleration would be 113 m/s ?

    Undergrad Speed loss per second due to air resistance

    Yes from what I've read it affects the drag coefficient and I intend to use a ballistic table for a similar shaped bullet to model it on. I just need the equation to calculate the speed lost per second due to drag.

    Undergrad Speed loss per second due to air resistance

    It's for a tank sabot shell, so once fired there wouldn't be any further force pushing it, if that changes anything?

    Undergrad Speed loss per second due to air resistance

    So you'd multiply the drag coefficient and the velocity to get the loss per second?

    Undergrad Speed loss per second due to air resistance

    Is there a formula covering this? (not including free fall/gravity) I have the drag coefficient, velocity and every other variable I think I would need for the object in particular.

    Archived AC Circuit Analysis for Complex Voltages and Impedances

    Was wondering if anyone can confirm that I am on the right track or not? I'm not sure whether Irms is meant to be a complex number not :/ Thanks in advance, otester Homework Statement A complex voltage v(t)=60sin(3wt)+15sin(3wt)+10sin(5wt) volts is applied to a coil of inductance 5mH and...
