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`

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 + (W)/(5)`

=>
`L_w = 50 + (35)/(5)`

=>
`L_w = 57 \ cm`
