Could someone please help me with this question I'm ever so stuck..
A spacecraft of mass 2000kg travelling at 100ms-1 seperates into parts A and B. As shown in the diagram above, A has a mass of 500kg and B a mass of 1500kg. After separation the speed of B is 150ms-1 in the original direction of motion.
a) Calculate the impulse acting on B in the separation.
b)Calculate the velocity of A after the separation.
c) Given that the seperation takes place over 75 seconds, calculate the average separating force.
B meets and attatches to a satellite C of mass 500kg travelling in the same direction as B with speed 130ms-1
d) Show that the velocity of the combined B and C is 145ms-1 in the original direction of motion.
Many Thanks!
