Asked by Iris PHYS
A ball thrown horizontally with speed vi = 26.0m/s travels a horizontal distance of d = 60.0m before hitting the ground. From what height h was the ball thrown?
Which I got this answer below.
h= 26.1 m
How do I solve for the one below.
If it takes a ball dropped from rest 2.308s to fall to the ground, from what height H was it released?

a. d = Vo*t = 60 m
26 * t = 60
t = 2.31 s. = Fall time.
h = 0.5g*t^2 = 4.9*2.31^2 = 26.1 m.
b. h = Same as part a.
