The one that's completely submerged is displacing more water, so the buoyant force on it is greater.
<span>A. Boyle's law only works when the pressure is constant.
</span><span>D. Charles's law relates volume and pressure.

Part A:
For this part we’re assuming all the kinetic energy of the moving bumper car is converted into elastic potential energy in the spring since the car is brought to rest. Therefore you can find the total kinetic energy to get your answer:
KE = ½ mv^2
KE = ½ (200)(8)^2
KE = 6400 J
Part B:
Now you can use Hooke’s law to find the force:
F = kx
F = (5000)(0.2)
F = 1000 N
