## Homework Statement

A force

^{2})

*x*

^{2}**i**is applied to a particle initially at rest in the

*xy*plane. Find the work done by this force on the particle and the final speed of the particle as it moves along a path as follows. The given force is the only force doing work on the particle.

a) in a straight line from point (2.1 m, 2.1 m) to point (2.1 m, 7.5 m)

_________ J

b) in a straight line from point (2.1 m, 2.1 m) to point (4.8 m, 6.6 m)

__________ J

## Homework Equations

W = F x d

## The Attempt at a Solution

a) Due to the equation that I found above, I have used the distance formula to calculate d:

= 5.4

Then I did F x d = 1.9 * 5.4 = 10.26 (Wrong)

b) Same this as above:

= 2.7

F x d = 1.9 * 2.7 = 5.13 (Wrong)

-------------------------------------------------

On top of these incorrect attempts, I am also confused with what the problem is asking... It says to find the word done by the force, and the final speed of the particle, but the answer boxes contain a J for Joules which is a unit of work. How would I put work and speed in one box?
