Ball launched off a cliff at negative angle...
So a ball is launched off a cliff 60 meters high
It is thrown at -15 degrees horizontal, and lands 120 meters away.
Find the V-initial, V-final, Time in air, and Angle at which it hits the ground
inverse tan(75)= Vx/Vy
D= VT
h=1/2g t^2
Vx= cosin(75) x V-initial
Vy=sin(75) x V-initial
I know that there's a policy that I have to try to work on the problem first before i get help, but man, I am lost. This is what I can make out.
I switched everything to positive so now its falling off the cliff at 75 degrees.
120 meters = Vx T
That's all. A little ray of guidance would be a Godsend.
PS
Would the Velocity-y be V-initial +34.6 m/s?
Because when something falls 60 meters from rest, the final velocity is 34.6 meters.
