Ich muss folgende formel herleiten. 2a_{2}*v_{2}+v_{1}+(m_{1} - m_{2}) u_{1} = m_{1}+m_{2} erklären sie das prinzip der beschleunigung eines satelliten mit hilfw von flyby auch schwingby gennant. ich muss mich mit dem thema impuls / impulserhaltungssatz beschäftigen. ich denke die formel kommt von der unelastische stoß. mit der frage 2 kann ich leider nichts anfangen. danke lg mara

To compare speeds speeds of wagons we will use second newton's law. it states: f = m * ahere we can see that force depends on the acceleration. if we know acceleration for both wagons we can compare them to make conclusion of speeds of wagons.we have: m1 = 10lbm2 = 20lbf1 = 2*f2also: m2 = 2*m1for bill we have equation: f1 = m1 * a1for tom we have equation: f2 = m2 * a2after inserting identities we have: 2*f2 =m1 * a1f2 = 2*m1 * a2in order to make conclusions about speeds we will solve these equations for a and find their ratio: a1 = 2f2 / m1a2 = f2 / 2m1a1 / a2 = (2f2/m1) / (f2/2m1)a1 / a2 = (2f2*2m1) / (m1*f2)a1 / a2 = (4f2m1) / (m1f2)a1 / a2 = 4this ratio is bigger than 1 and this means that a1 is greater than a2. a1 is 4 times greater than a2. speed of bill's wagon is 4 times greater than speed of tom's wagon.
