hf=hi+vi*t -1/2 * 3.7*t^2
hf=0,hi=245, vi=0 solve for time t
vf=3.7m/s * time
A robot probe drops a camera off the rim of a 245 m high cliff on Mars, where the free-fall acceleration is 3.7 m/s2.
Find the velocity with which it hits the
ground. Answer in units of m/s.
2)Find the time required for the camera to reach
the ground.
Answer in units of s.

V^2 = Vo^2 + 2gad,
V^2 = 0 + 2 * 3.7 * 245 = 1813,
V = 42.6 m/s.
2. d = 0.5at^2 = 245 m
0.5 * 3.7 * t^2 = 245,
1.85 * t^2 = 245,
f^2 = 245 / 1.85 = 132.4,
t = 11.5 s.
V^2 = 0 + 2 * 3.7 * 245 = 1813,

I don't know and nor do you cause yk why? all of us is dumb :).
