19. Decomposing Thrust Vectors

C3 C1 L16 Decomposing Thrust V2

In the image above, the thrusts from the two propellers have been combined into a single F_{\text{thrust}}. For the following questions assume the quantities shown above have the following values (in standard units):

Quantity Value
m 10
F_{\text{thrust}} 120
\phi 30^{\circ}

Which of the following expressions gives the total force in the horizontal y direction F_y for this vehicle?

SOLUTION: F_y = F_{\text{thrust}} \sin \phi

What will be the resulting acceleration in the y direction \ddot{y}?

SOLUTION: 6 m/s^2
