Apencil is dropped, point down, into water. if the pencil is released from a height of 0.04 nm (measured from the point to the water level), how far will it dive? treat the pencil as a cylinder of radius 0.40 cm, length 20 cm, and mass 4.0 gm. ignore the frictional and inertial resistance of the water, but take into account the buoyant force. hint: draw a neat sketch in which all variables, etc, are well defined, and then, using an appropriate free body diagram, make use of newton's 2nd law and write the acceleration in the form a v (dvldy)- a 1a rule when f is a function of y
