**1. Homework Statement**

Until his seventies, Henri LaMothe excited audiences by belly-flopping from a height of 12 m into 30 cm of water. Assuming that he stops just as he reaches the bottom of the water and estimating his mass, find the magnitude of the impulse on him from the water.

**2. Homework Equations**

v^2 = vo^2 +2ay

j = pf - pi

p = mv

**3. The Attempt at a Solution**

y = 12.3

a = 9.8

from equation 1, Vf = 15.53 m/s

from equation 2 and 3 J = 15.53m -0m = 15.53m

Help please.
