Unformatted text preview: f. How many nuclei undergo fission? g. If each fission releases the energy you calculated in part (d), how much energy is released by the bomb (convert from MeV to Joules to kiloTons)? h. How many generations were involved in the chain reaction? i. If the average time for a neutron to reach a U nucleus and subsequently to induce fission in a critical mass is 108 sec, how long will it take to "burn" all the U nuclei that underwent fission in the bomb? II. A single shortrange missile is accidentally launched vertically from a launching tube. Its initial velocity upward as it leaves the tube is 400 m/s. a. What is its Kinetic Energy when it reaches its highest point? b. How high does it go (ignoring air resistance)? c. After it reaches that highest point, how far does it fall in 10 sec.? d. What is the missiles speed at that time (10 sec after the highest point was reached)?...
