## Homework Statement

Three forces acting on an object are given by F1 = ( 1.55 i - 1.90 j ) N, F2 = ( - 5.20 i - 3.15 j ) N, and F3 = ( - 50.0 i + 44.0 j ) N.

(a) What is the direction of the acceleration?

° (from the positive x axis)

(b) What is the mass of the object?

kg

(c) If the object is initially at rest, what is its speed after 16.0 s?

m/s

(d) What are the velocity components of the object after 16.0 s?

( i + j ) m/s

## Homework Equations

F=ma

## The Attempt at a Solution

the acceleration is 3.70 m/s2. i know to get the direction in part (a) i have to use arctan ay/ax but i can't figure out how to get those values. the velocity is 59.2m/s but i don't know how to get the unit vectors.
