A 1.2-kg spring-activated toy bomb slides on a smooth surface along the x-axis with a speed of 0.50 m/s. At the origin O, the bomb explodes into two fragments. Fragment 1 has a mass of 0.4 kg and a speed of 0.9 m/s along the negative y-axis. 0.8 kg 0.5 m/s O- 0 X 1.2 kg 0.4 kg Before After 0.9 m/s 1) State which type of "collision" this is (elastic or inelastic), (1 pt) 2) Which quantity or quantities are conserved and why? (kinetic energy, momentum, velocity) (1 pt) 3) Calculate the angle of particle 2 after the explosion (using the conservation law that applies). (4 pts) 3) Calculate the final speed of particle 2. (4 pts) Type your answers in the box, but submit your work to Test 3 Written Word dropbox
