On the reverse page is pictured part of a collision between two dry-ice pucks A and B (m,= m, = 300 g). The collision takes place using magnets and is captured using a strobe light that flashes 10 times a second. The centre of each puck is indicated using a small circle and the path of puck B has been erased. PuckB was initially at rest and was positioned at the small circle near the letter B. The image is shown to scale. Hints: Choose a convenient coordinate system for your measurements Indicate your sign convention Show your results on the front page and your work on this page.
