Pressure problem -- Impulse of object striking a head 1. A police crime lab is trying to determine whether someone was murdered or died as a result of an accident. He was struck in the temple by a 4.20 kg sculpture that is alleged to have fallen off a bookcase. The sculpture presumably fell a distance of 1.43 m and the corner that struck him had an area of 0.25 cm2. If the time for the sculpture to stop was 1.00 ms, the pressure on his temple, in N/m2, was... 2. i know pressure is : p=F/A A(area)= 2.5*10^(-5)m^2 and the answer is p=8.88*10^(8)N/m^2 but i cant get force in any way i know its F=ma, but whatever i try doesnt work. please help.
