Question

If an object is dropped, how fast will it be moving after falling `1 m`?

Answer 1

`4,427m//s`

Explanation:

Object is in free fall so only force acting is gravity (assuming no friction or air resistance) so equations of motion for constant linear acceleration in 1 direction are valid :

`therefore v^2=u^2+2ax`

`therefore v=sqrt(0^2+(2xx9,8xx1))`

`=4,427m//s`.
