[@bahadursinghsolanki3796]

To simulate car accident, auto manufacturers study the collisions of moving cars with mounted spings of different spings constants. Consider a typical simulation with a car of mass of 1000kg moving with a speed 18 km/h on smooth road and colliding with a horizontally mounted spring of spring constants 5.25×10^3 N m^-1. What is the maximum compressoin of the spring????

[@seemabhagat7459]

By my calculations it's 2.18 . I used 1/2mv²=1/2kx²

[@seemabhagat7459]

I think that the value of k must be 6.25 × 10³ to make calculations easier . If value of k is equal to 6.25×10³then X= 2

Gvn sir, I am from lakshya jee 1.0 Sir , agar block ke karan spring h jo max compress hota h to spring apna shape regain karna chachega to kitna force spring block pe lageye ki block max distance travel kar sake(jis se spring apna shape bhi regain kar le aur block max distance bhi travel kar le). Sir , how to find these type of force?

Tension or normal ka net work done zero Internal forces work done kr skti hai koi dikkat nahi pr acceleration nahi dengi acceleration humesha external forces ke wajah se hi aayega Kuch atpatang si force ka work done pucha ho to use sidha integrate krdenge Chahe maximum compression puche ya maximum elongation puche maximum velocity puche ya speed puche ya omega puche work energy theorem hi lagega
