A Child on a sled is being pulled along a horizontal path by its parent at a constant velocity. The child and sled have a combined mass of 20 kg. The parent pulls with a force of 125 N at an angle
of 38 degrees above the horizontal. Solve for all unknown forces.

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.
