Question from matlab Worksheet:

How would you code and solve this in matlab ?

Thank you.

Suppose you work for a company that produces packaging. You are told that a new packaging material can protect a package when dropped, provided that the package hits the ground at less than 25 ft/sec. The package’s total weight is 20 lb, and it is rectangular with dimensions of 12 by 12 by 8 in.

You must determine whether the packaging material provides enough protection when the package is carried by a delivery person.

To provide your answer, create a variable ep = 'yes' or 'no'

[Hint: estimate the maximum height (h) the package can fall from neglecting the air drag]

Hello Thomas --

As this is your homework assignment. Therefore we cannot provide you with a direct answer due to plagarism. However, here are the steps that you can follow:

1. Convert the dimensions of the package to consistent units (e.g., inches to feet) for the calculations.
2. Calculate the potential energy of the package when it falls from the maximum height (h) using the formula PE = mgh, where m is the mass of the package and g is the acceleration due to gravity.
3. Calculate the velocity of the package when it hits the ground using the formula v = sqrt(2gh), where h is the maximum height.
4. Check if the velocity is less than 25 ft/sec.
5. Set the value of the variable "ep" to 'yes' if the velocity is less than 25 ft/sec, or 'no' otherwise.

I hope this helps.

Hello Tusharr,

thank you for the explanation.

I will try these steps as recommended.

As far as I can tell, his steps 1 and 2 are not necessary. You simply need his formula from step 3.
