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

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
