A ball of mass 400 g and a volume 100 cm³ is released from rest just under the surface of a lake of fresh water.
a) Find the buoyant force acting on the ball. [Hint: Be careful with units.To find aweight in newtons, you must use SI units for g (10 m/s²) and for the mass.]
b) Find the acceleration of the ball right after it has been released.
m= 400g
V=100cm³
BF=Weight of water displaced
