Question
2) A rocket is shot straight up to a height of 120.0 m where it explodes causing the rocket to split into two parts that weigh ma=2.40 kg and me=0.55 kg respectively. 1380 J of chemical energy was transformed into kinetic energy of the two parts (i.e., 1380 J= KA + Kg). a) What is the speed of each part, vA and vB, just after the explosion? b) What is the time taken for the parts to reach the ground after the explosion?(It is observed that the two parts hit the ground at the same time) c) What is the distance between the points on the ground (d) where they land? (Assume that the ground level and neglect air resistance). Object B Object A VA and ma Va and ma h= 120.0 m
