For this problem, we are asked to explain what happens when we change the height from which we launch a projectile.
00:06
So for 16, the change that that would have, if we imagine some projectile arc, then we change that.
00:16
So now we're launching it from a greater height.
00:20
What we'd have is that the projectile is going to have a greater maximum height, and it's going to spend longer in the air.
00:33
It will spend longer in the air as well as going horizontally further additionally.
00:39
Then, for question 17, we're asked if a light mass and a heavy mass are launched at the same angle with the same velocity, which mass will reach the ground first.
00:48
So, the answer here is neither.
00:54
Unless we account for things like air resistance, we'd have that both have the same acceleration due to gravity...
