a - 12 m/s^2

b - 8 m/s^2

c - 5 m/s^2

d - 15 m/s^2

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

50 meters per 5 seconds
