The balls are released from rest at a height of 5.0m at time t=0s. How long [tex]t_g[/tex] does it take for the balls to reach the ground? Use 10 m/s^2 for the magnitude of the acceleration due to gravity.(adsbygoogle = window.adsbygoogle || []).push({});

i'll use the position formula for this problem:

[tex]y = y_0 + V_{y_0}*t - 1/2*g*t^2[/tex]

well i know that

[tex]y_0[/tex] = 5.0 m

g = 10 m/s^2

i'm missing [tex]V_{y_0}[/tex]

if i plug in t = 0, wouldnt it just cancel everything out? but it doesnt make sense.
