Answer 1

Complete Question

A certain 50 cm spring will stretch (in  cm) one fifth  the weight (in kg) attached to  it. How long will the spring be if a 35  kg weight is attached to it

Answer:

The value is $L_w = 57 \ cm$  

Step-by-step explanation:

The length of the spring is $L = 50 \ cm = 0.5 \ m$

 The  mass attached to it is  $w = 35 \ kg$

Generally given from that the spring will stretch one fifth of the weight  (in kg)attached to it , it then means that the  new length of the spring whenever a weight is attached to it is mathematically represented as

          $L_w = L + \frac{W}{5}$

=>      $L_w = 50 + \frac{35}{5}$  

=>      $L_w = 57 \ cm$
