Problem
A 2.0kg aerial shell travels due north at 40m/s when it is triggered to burst apart into two fragments while still in flight. The smaller fragment has a mass of 0.50kg and is observed to continue through the air at 60m/s along a line 45∘ west of north. Air resistance and gravity may be neglected during the extremely brief explosion event.
(a) Determine the north and east components of the momentum of the 0.50kg fragment immediately after the explosion.
(b) Using the result from part (a), find the north and east components of the momentum of the larger fragment right after the explosion.
(c) Calculate the speed of the larger fragment and state its direction of motion relative to due north.
