First solve the vertical plane problem.
How long does it take to drop from 2 meters ? It has zero initial velocity down.
-2 = 0 + 0 t +(1/2)(-9.8) t^2
t^2 = 4/9.8
t = .64 seconds in the air
then distance = speed * time
21 = speed * .64
thankyou!!
wait i believe this is not my problem? mine is the cannon problem
Same problem, different numbers
