## Homework Statement

A force F = 8i-3i N acts on a particle that undergoes a displacement Δr = 2i + j m.

(b) What is the angle between F and Δr? (state your answer to three significant figures)

## Homework Equations

Angle = cos-1 (A.B/ AB)

## The Attempt at a Solution

W=13.1 J

AB= 8.5*2.23= 19

cos-1 (13.1/19)= 46.4
