- I need to find the appropriate launch angle that will land an object 65 meters north of my position. Therefore Δdx = 65m [N](adsbygoogle = window.adsbygoogle || []).push({});

- I am told that the time the object take to hit the ground is 5.23 seconds. Therefore Δt = 5.23s

- I then used the equation Δdx = v1xΔt to find v1x = 12.43 m/s.

After this I haven't a clue what to do next. Would someone kindly outline the steps I need to take to find the launch angle. Muchas gracias.
