Question

* A body falling freely from the top of a tower travels 50m
in the last second before it reaches the ground. What is
the height of the tower?​

Answer 1

Answer:

We have defined the object's final vertical position as 0m at the ground, and therefore we obtain a negative change in position from the top of the tower to the bottom. ∴ The tower is ≈128m tall.

Answer 2

Explanation:

s=ut+1/2 gt^2

find u,

using v^2=2gs+u^2

s=50m

find v,

find S using v^2 - 0 =2gS

S is height of the tower.... at the top velocity is 0
