Answer:
thanks for the five points
I think i used calulater and it gives me 47.5
Electronssssssssssssssssssssssssssss
The relevant equation we can use in this problem is:
h = v0 t + 0.5 g t^2
where h is height, v0 is initial velocity, t is time, g is
gravity
Since it was stated that the rock was drop, so it was free
fall and v0 = 0, therefore:
h = 0 + 0.5 * 9.81 m/s^2 * (4.9 s)^2
<span>h = 117.77 m</span>
Answer:
all of above I think sorry if I'm not right but I tried
