Answer:
These two objects hit the ground at the same time. But their impact velocity will be different
because they are dropped from different heights.
The one that is dropped from the building will have more impact when it hits the ground because gravity causes this onject to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2.
Step-by-step explanation:
Initial velocity of the object u=0
Final velocity of the object when it reaches the ground v=A m/s
Using v^2−u^2=2gS where g=10m/s^2
A^2 −0^2=2(10)H
A^2=20*H H- heigh from the table
Object falling from the building will have the same initial velocity but different heigh.
T>H
so
B^2=20*T
20*T>20*H
so B^2>A^2
it equal to B>A so object falling from the building will have more impact than falling from the table.
