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.
