Question

The acceleration of free fall on a particular planet is 8.0 m/s². An object is dropped from a height and hits the ground after 1.5 seconds. From what height was it dropped? PLEASE ANSWER ASAP! URGENT! ⚠️

Answer 1

Given:-

•Initial velocity(u)=0

•Acceleration due to gravity(g)=8m/s²

•Time=1.5s

To find:-

•Height from which the object was dropped(h)

Solution:-

By using 2nd equation of motion,when u=0,we get----

=>h=1/2gt²

=>h=1/2×(8)×(1.5)

=>h=4×2.25

=>h=9m

Thus,the object was dropped from a height of 9m.
