    Rocket Thrust, Acceleration, Velocity and Altitude

    Oh it came from https://www.google.com.au/webhp?sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#q=distance%20calculator%20physics&safe=off except I tried to put gravity on the end of it. The course unit is Physics of Games (seconds year uni subject), there were no prerequisites for...

    What is the Separation of Two Apertures in a Light Diffraction Grating?

    Ahh second order, I had m = 0 which is zeroth order. So m should equal 2?

    What is the Separation of Two Apertures in a Light Diffraction Grating?

    Homework Statement A source of light shines through two apertures resulting in an intensity distribution pattern on a viewing screen. The central bright fringe is called the m=0 or zeroth order maximum. In the schematic diagram 1, the light source is to the left of the page and the point...

    Rocket Thrust, Acceleration, Velocity and Altitude

    v = v0 + u * ln(M0 / Mt) - gt I put the subscript on the first M, 0 for the original mass, then the subscript t on the second for mass at the given time; M1 = 3625 (d) Calculate the altitude reached after 1 second. x = v0t + 0.5 * at2 - gt a = 150,000 / 3625 - 10 = 31.38 x = 0 + 0.5 *...

    Rocket Thrust, Acceleration, Velocity and Altitude

    Not really sure what, or how to establish a general formula for 'net acceleration'. I reworked my equation including gravity and fixing the log/ln problem: v = v0 + u * ln(M0 / M) - g v = 0 + 400 * ln(4000/3625) - 10 v = 400 * 0.09844007281 - 10 v = 29.38 m/s How's this?
