a ball is kicked at an angle of 50 degrees at a speed of 25m/s. when it passes a 3m tall bar 30m away will it be above or below the bar?
are these variables right? if not what are they?
x:
d=30m
di=0m
v=?
vi=?
t=?
a=0m/s
y:
d=3m
di=0m
v=?
vi=0m/s
t=?
a=10m/s
how do you solve this?

no, they are not right,
the following is wrong
y:
a = -10 m/s^2
otherwise your answer is certainly 'above'.
