time to go 60 m
time=60/40cos40
now, how high at that time?
h=40sin40*t-4.9t^2
landing pad?
find the time of impact
hf=Vsin40t-4.9t^2 when hf=0,solve for time.
then, distance=40cos40*t
Zandor is being shot out of his cannon (at a velocity of 40 m/s) at an angle of 40 degrees above the horizontal. He is planning to pass through a ring of fire (which is 60 m from where he starts) to the landing pad. How far is the ring of fire from the ground? How far is the landing pad from where he starts?
