Calculating Velocity A ball is released from the top of a hill. How fast is the
ball going when it reaches the base of the hill?
Approximate g as 10 m/s2 and round the answer to the
nearest tenth.
m/s
h = 2 m
h = 0.5 m

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.

Centrapedial force is the answer
