Question

A girl of mass 48.0 kg is rescued from a building fire by leaping into a

Answer 1

Answer:

mgh = 1/2 mv^2

So, v^2 = 9.81*12*2 = 235.44

her momentum upon impact was p = mv = 48 * 15.34 = 736.51 kg-m/s

So, ∆p = -736.51 kg-m/s

maybe you want the rate of change of p. In that case, just divide by 0.45s
