1. A space probe is launched vertically into space. It launches from rest and accelerates at a rate of 29 m/s2. How many seconds before the probe reaches the speed required to get into orbit, 7,850 m/s? (round to the nearest tenth)

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.
