1. I have a ball that is thrown off a 3m high cliff at 20 m/s horizontally, what is the displacement on the X axis, Vf, and tair? (assuming no air resistance) 2. Relevant equations d=Vi*t+(1/2a*t2 3. The attempt at a solution When I tried to solve this problem I couldn't really find an equation that worked. I'm confused about how to find the time in the air with the given information, do you guys know any other formulas that would be helpful for this problem?
