Homework Help Overview
The problem involves kinematics, specifically analyzing the fall of an object under the influence of gravity. The scenario presented is about determining the height from which Humpty Dumpty fell, given the time of the fall.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- Participants discuss the nature of Humpty Dumpty's fall, questioning whether it involves constant velocity or acceleration. There is mention of free-fall and the initial conditions of the motion.
Discussion Status
Some participants have provided equations related to the problem, while others express uncertainty about the assumptions regarding the motion. There is an indication that attempts have been made to apply the kinematic equations, but clarity on the motion specifics remains a topic of exploration.
Contextual Notes
There is a lack of explicit information about the initial velocity and the nature of the fall, which participants are considering in their reasoning.

The policy here is that you have to show your attempt at a solution. How does Humpty-Dumpty move? with constant velocity? Or does he accelerate?

It seems like a case of free-fall.
u=0,a=g and t is given
Use the equation H=ut+1/2at2
But this is what I presume.There isn't any clear information about the motion of Humpty Dumpty.

Thanks, I got it.
I used H=ut+1/2at2
but it seemed I was inputting the wrong digit to the calculator
