4. ### Model Airplane math questions?

a) The shape is a parabola, so it's minimum height would be at the vertex. The x value of the vertex is found using x = -b/2a x = -(-12)/(2*1) = 6 sec y(6 sec) = 6^2 - 12(6) + 40 y = 4 m b) Initial height is when t = 0. y(0 sec) = 0^2 - 12(0) + 40 y = 40 m c) 40...

5. ### Airplane Math Question?

Let S = speed of plane and W = speed of wind Distance = effective speed x time For the journey out 2400 = (S + W) x 6 or S + W = 2400 / 6 = 400 or S = 400 - W For the journey back 2400 = (S - W) x 8 or...

6. ### Vectors help with a airplane?

The Law of Sines can help determine course and airspeed. The desires flight path has a 35 degree variance from the headwind pushing it north, so the angle between the wind and path is 145 degrees. The gross path has a magnitude of 200 and...

8. ### Determine the speed of an airplane?

Let v = speed of wind speed of plane on the first part of the trip = 600 + v speed of plane on the return trip = 600 - v time for the first part of the trip = distance/speed = 990/( 600 + v) time for the second part of the trip = 990 / (600 - v) total time for the round trip is 990/( 600 + v) + 990 / (600 - v...

9. ### How fast did each of the airplanes travel?

d = vt vt = 1000 => t = 1000/v (v + 50)(t - 1) = 1000 (v + 50)(1000/v - 1) = 1000 v = 200 v + 50 = 250
