Question

An object with a mass of `3 kg` is on a plane with an incline of `pi/12`. If the object is being pushed with `8 N` of force, what is the net force on the object?

Answer 1

Resolving parallel to the plane we have:

`3gsin(pi/12)` Newtons acting down the plane due to gravity

and 8 Newtons acting up the plane

Hence, net force is `8 - 3gsin(pi/12)`

i.e. `8 - 7.609279926 => 0.39` Newtons up the plane
