sec. 14-7 Archimedes' Principle - 30 A \( 5.00 \mathrm{~kg} \) object is released from rest while fully submerged in a liquid. The liquid displaced by the submerged object has a mass of \( 3.00 \mathrm{~kg} \). How far and in what direction does the object move in \( 0.200 \mathrm{~s} \), assuming that it moves freely and that the drag force on it from the liquid is negligible?

A 5.00 $\mathrm{kg}$ object is released from rest while fully submerged in a liquid. The liquid displaced by the submerged object has a mass of 3.00 $\mathrm{kg} .$ How far and in what direction does the object move in 0.200 s, assuming that it moves freely and that the drag force on it from the liquid is negligible?
When a boat is partially immersed in water, it displaces 600 kg of water. How much is the buoyant force acting on the boat in newtons ? (g = 10 m s-2)
Aman K.
An object of mass 100 kg is released from rest from a boat into the water and allowed to sink. While gravity is pull- ing the object down, a buoyancy force of 1>40 times the weight of the object is pushing the object up (weight = mg). If we assume that water resistance exerts a force on the object that is proportional to the velocity of the object, with proportionality constant 10 N-sec/m, find the equation of motion of the object. After how many sec- onds will the velocity of the object be 70 m/sec?
