If we eliminate angle d, the resulting equation is: h = (L * tan a * tan c) / (cos b * (tan b + tan c)). If V_y - g * t (v_y = 0) = 0, then we can transformed this equation to: t (V_y=0) = V_y / g Now, find the vertical distance from the surface at that time: He says that Musk literally taught himself rocket science by reading textbooks and talking to industry heavyweights. And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter. This equation applies to launching the rocket off the launch pad. trigonometric functions Since we know the initial and final velocities, as well as the initial position, we use the following equation to find y: v2y=v20y2g(yy0). 1 0 obj The cookie is used to store the user consent for the cookies in the category "Other.
