This problem has been giving me problems for the past two days and I can't figure it out :( please help. this is my first ever physics class.
A rubber ball is shot straight up from the ground with speed v_0. Simultaneously, a second rubber ball at height h directly above the first ball is dropped from rest.
Known:
V_0 and Height of origional ball drop
y_coll= h- ((gh^2)/(2v_0)^2)
find:
h_max
Vx= Vxi+ax (tf-ti)
Xf=Xi + Vxi + 1/2 ax (tf-ti)^2
Vxf^2= Vxi^2+ 2ax (Xf-Xi)
I got to the point where I found what I thought was h_max and got
hmax= (V_0^2/g)- 1/2*V_0^2
the website I am working on told me I am missing a term but I can't figure out what I am missing. :(
