If a 1megaton nuclear weapon is exploded
at ground level, the peak overpressure (that
is, the pressure increase above normal atmo
spheric pressure) will be 0.2 atm at a distance
of 6 km.
What force due to such an explosion will be
exerted on the side of a house with dimensions
4.39 m × 33.5 m?
Answer in units of N

physics 
bobpursley,
force= pressure*area= .2atm(101.3kPa/atm)*4.39*33.5 m^2
do all that, and force will be in Newtons. (Pa pascal is a newton/m^2)
