    How Do You Calculate the Mass of the Plane After Intercepting Luggage?

    Homework Statement A plane with an initial velocity of (225m/s ŷ + 325m/s Ẑ) intercepts a 20kg piece of luggage with initial velocity of (-75m/s ŷ - 15m/s Ẑ). After, plane is moving at speed 400 m/s. What is the mass of the plane? Homework Equations momentum y: Mplane(225m/s) + 20kg(-75 m/s) =...

    Pulley suspending two different masses lifted upwards

    The force F pulls upwards two masses, m1 and m2(m2>m1), which are connected to each othet via a massless pulley. The masses are perched on the ground before movement starts. A. What is the acceleration of each one of the respective masses in each of the following situations: 1)F<2*m1*g...
