hi, thanks a bunch for your reply. Ok, so my V[SUB]i[SUB] in components is V[SUB]i[SUB][SUB]x[SUB]=V[SUB]i[SUB] cos(45)
&
V[SUB]i[SUB][SUB]y[SUB]=V[SUB]i[SUB]sin(45)
...
Ok, and time can be written as:
t =( V[SUB]f[SUB][SUB]x/y[SUB] / a) + V[SUB]i[SUB][SUB]x/y[SUB]...
Discern initial V w/o components!?
Homework Statement
Ok, ball traveled 188m (618 ft) before landing on the ground. Assume ground is flat, and ball Vi is from 45o, disregard air resistance, and Starting position is .9m above ground.
Find Vi
I KNOW )))) a= 9.8 m/s2...
