Vertex is (-2,-3) and it's a minimum.
Answer:
23.7m
Step-by-step explanation:
Given parameters:
Time taken = 2.2s
Acceleration due to gravity = 10m/s
Unknown:
Depth of the well = ?
Solution:
To solve this problem, we simply apply one of the motion equations;
S = ut +
gt²
where S = depth of the well
u = initial velocity
t = time taken
g = acceleration due to gravity
Input the parameters and solve for S;
Note initial velocity = 0;
S =
x 9.8 x 2.2²
S = 23.7m
I’m so sorry if some of them are wrong, I haven’t did this in a few years but I’m pretty sure almost all of them are right.
