Question: A model airplane is making a right turn. Its mass is m = 120.0 kg , The magnitude of the gravitational acceleration is 9.80 m/s2
A model airplane is making a right turn. Its mass is m = 120.0 kg , The magnitude of the gravitational acceleration is 9.80 m/s2 . The speed is 20.39 m/s . The angle = 22.0 Check that the angle in your calculator is in "degrees", sin30o = 0.5. Choose +x pointing toward the center of the circle. Choose +y upward. Part A - The lift force L : its magnitude is unknown. Here we use a space holder for magnitude L. Based on " +x pointing toward the center of the circle. +y upward", which of the following is the correct way to write its x- and y- components of L ? L x = - L cos( ) L y= L sin( ) L x = - L L y= 0 L x = L L y= 0 L x = - L sin( ) L y= L cos( ) L x = 0 L y= L L x = Lcos( ) L y= Lsin( ) L x = 0 L y= - L L x = Lsin( ) L y= L cos( )
