## Homework Statement

A mass at rest of 70 Kg receives a force underneath of 360 N. Calculate the height of the mass when 2 seconds have passed.

## Homework Equations

1) F = m.a

2) Y(t) = g/2*t^2 + Vi*t + Yi

## The Attempt at a Solution

This is a problem i need to solve in order to start something in my thesis.

With force and mass we obtain the acceleration of the mass that is equal to 360/70 = 5.14 m/s² (formula 1). My problem is, since this is a vertical problem, the gravity is present and the formula 2 cannot be used with this acceleration.

Happening this and many other things I've tried, this might be a problem that has to be solved with Energy formulas. The problem of that is, my coursework of Physics in my Computer Science career has a really poor content of Work and Energy so i kinda need some tuition here.

The problem looks really simple to my brain, but not for the paper and the formulas.

Looking forward for some help,

Peter.
