2.Using the kinematic equations, prove that if two balls are released simultaneously from a table, one with zero velocity and the other with a horizontal velocity Vox, they will both reach the ground at the same time.

Only Voy matters in the verical equation of motion.
The vertical height at time t is
y = H + Voy*t  (g/2) t^2
In both cases, Voy = 0.
When the height y = 0,
t = sqrt(2H/g)
H is the height of the table.
