Halliday, Resnick & Walker β Kinetic Energy and Work: Problem 4
An explosion at ground level leaves a crater with a diameter that is proportional to the energy of the explosion raised to the $1/3$ power; an explosion of 1 megaton of TNT leaves a crater with a 1 km diameter. Below Lake Huron in Michigan there appears to be an ancient impact crater with a 50 km diameter. What was the kinetic energy associated with that impact, in terms of (a) megatons of TNT (1 megaton yields $4.2 \times 10^{15}\text{ J}$) and (b) Hiroshima bomb equivalents (13 kilotons of TNT each)?
π Solution Approach
Given: 1 km, 50 km, , in
Find: (a) megatons of TNT; (b) Hiroshima bomb equivalents
