    thanks...otherwise I was totally confused.

    They simulations give the same answer. My concern is that whether it is off the ground or off a cliff, you still get the same range. Is that right? Shouldn't it be further for the scenario off the cliff?

    I used the one above "Will it clear the fence?" and then "Where will it land?" for the cliff scenario. initial velocity of 15 m/s at 40 degrees and then a cliff height of 3 m. Now I did just notice that if you add the two x components, it equal the answer from the first one but shouldn't...

    I just compare the two scenarios using the simulations. The first one was the box right above "Will it clear the fence?" The second one was "Where will it land?" a couple of boxes down. I used Vi of 15 m/s and angle of 40 degrees and a height of 3 m for the second one. Now I just...

    Why does a projectile sitting on the ground travel further than a projectile launched on a cliff? As per HyperPhysics it said that sitting on ground a projectile at 15m/s and 40 degrees above the horizontal would travel +22 m but if you put on top of a 3 m high cliff, the range would be...
