Momentum (p) = mass (m) x velocity (v)
We know the velocity of Jennifer which is 1.22 m/s. Therefore, we need to find her mass to calculate her momentum. To find her mass, we divide her weight by the acceleration due to gravity (g=9.8 m/s^2):
Mass (m) = weight (w) / acceleration due to gravity (g)
Mass (m) = 552 N / 9.8 m/s^2 = 56.3 kg
Now we can calculate her momentum:
Momentum (p) = mass (m) x velocity (v)
Momentum (p) = 56.3 kg x 1.22 m/s = 68.6 kg m/s
Therefore, the answer is (C) 68.6 kg m/s.
