A 0.850 kg air-track glider moving at 1.75 m/s bumps into a 1.45 kg glider initially at rest (a) If the collision is elastic, find the total kinetic energy after collision.
(b) If the collision is completely inelastic, find the total kinetic energy after collision

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.

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d
