Homework Statement
The diagram to this problem is of a HILL as shown:
Point A
-
-
20m
-
-
------------------------50m------------------------- Point B
From ground level, a person at Point A throws a snowball horizontally to the right at 25 m/s. Where does the snowball land?
a) 10m to the left of Point B
b) At Point B
c) 12.5m to the right of Point B
d) 50m to the right of Point B
Homework Equations
According to the answer given (answer is B), the relevant equations are t=(2h/g)^(1/2) and d=vt
The Attempt at a Solution
The 4 linear motion equations I know are
x = x + vt + (1/2)at^2
v(initial) = v(final) + at
v(i)^2 = v(f)^2 + 2ax
v(avg) = (v(i) + v)/2
I don't know the time equation listed in the answer. Is it derived from one of these equations or is it a whole different equation? I'm confused about how I was supposed to know to solve this question basically...
