An object with a mass of #5 kg# is hanging from a spring with a constant of #3 (kg)/s^2#. If the spring is stretched by #6 m#, what is the net force on the object?

Answer 1

The net force is #=31N#

Mass of object #m=5kg#

The spring constant is #k=3kgs^-2#

Extension of the spring is #x=6m#

Resolving in the vertical direction #uarr^+#

The net force is #F=6*3-5g#

#=18-5g=-31N#

There is a net force of #31N# acting downwards

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
