Final answer:
The Mk 62 mine weighs approximately 1500 lbs.
Step-by-step explanation:
The weight of the Mk 62 mine can be estimated by using the information provided regarding the weight of nuclear fuel and warheads carried by missiles. According to the data, the nuclear fuel of the missile totals only 6 kg, and it is reasonable to assume that some missiles carry 10 warheads. The mass of the 10 warheads would be 10 times the nuclear fuel, weighing about 1500 lbs (based on the assumption that the fuel weighs 5 times the total weight of the warheads). Therefore, it can be inferred that the Mk 62 mine weighs approximately 1500 lbs.
