Question

An object with a mass of `4 kg` is hanging from a spring with a constant of `2 (kg)/s^2`. If the spring is stretched by `2 m`, what is the net force on the object?

Answer 1

`F_n=35,24 N`

Explanation:

`"Gravity of object is : " color(red)(G=m.g=4. 9,81=39,24 N)`
`"Force on spring is : "color(navy)(F=K. Delta x=2.2=4 N)`
`"Net Force on the object is: "F_n=color(red)(G)-color(navy)(F)=39,24-4`
`F_n=35,24 N`
