Answer:

Explanation:
Natural length of the string is given as

length of the string while block is hanging on it

extension in length is given as

now we have strain in the string is given as



similarly we will have cross-sectional area of the string is given as

now the stress in the string is given as




Now Young's Modulus is given as



Answer:

Explanation:
From this exercise, our knowable variables are <u>hight and initial velocity </u>


To find how much time does the <u>ball strike the ground</u>, we need to know that the final position of the ball is y=0ft


Solving for t using quadratic formula


or 
<u><em>Since time can't be negative the answer is t=6.96s</em></u>
