A small ball (ball 1) is released from rest; i.e. dropped, at
the origin (0,0) and falls freely. At the same time another ball
(ball 2) leaves the same position with an initial
horizontal velocity of 2.70 m/s.
Calculate the time it takes ball 1 to fall 3.50 m.
What is the time it takes ball 2 to fall 3.50 m?
Calculate the horizontal distance ball 2 will move during this
time.
Calculate the vertical component of the velocity of ball 1 after it
has fallen 3.50 m.
(magnitude - Remember that the magnitude of a vector is always
positive)

A small spherical ball of density p and radius a is released from rest and falls under gravity in a viscous liquid of density pf and viscosity u. Its vertical position is denoted by z(t), and we choose the origin such that z(0) = 0. The ball is subjected to two forces: its weight corrected for buoyancy F, = (p-p Vg, where g is the acceleration of gravity pointing in the - z direction and V = 47a/3 is the...
