A freely falling body, falling from a height of 2km, and assuming g = 10m/s2, will strike the ground in a time of
- 40s.
- 80s.
- 20s.
Asuka16 asking:
Can you give me the formula for this?

s = ut + 1/2 a t^2
Assuming from rest(at 2km), ut is remove, so s=½at²
Assuming from rest(at 2km), ut is remove, so s=½at²
