The discussion clarifies why an object falling 10 meters at an initial speed of 10 m/s takes 1.4 seconds to land, rather than just 1 second. Using gravitational acceleration (g) of 10 m/s², the object starts from rest, resulting in an average speed of 5 m/s during the first second, allowing it to fall only 5 meters. The remaining distance is covered in the subsequent 0.4 seconds as the speed increases due to gravity.

Taking g = 10 m/s2, after 1 second the speed will be 10 m/s. But realize that it started from rest, so the average speed during that first second is only 5 m/s, thus it only fell 5 meters during that first second.tbbyrd said:If somthing falls 10 meters (at 10m/s), ignoring air resistance, why does it take 1.4s to land instead of just one?
I suppose i am simply having a brain fart but this is bothering me...
