Answer 1

sorry, I don't know this question

please mark me as brainiest

Answer 2

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
