## Homework Statement

"Consider the 65.0-kg ice skater being pushed by two others as shown in the figure below."

Figure: https://gyazo.com/9d7525071f54b00ea7e720abdeb50594

Find the total force exerted on her by the others, given that F1 = 21N and F2 = 36N. Express your answer in vectorm form.

## Homework Equations

I doubt "F=ma" is relevant for this question considering we're merely calculating the force directed towards the skater instead of her movement thereafter.

## The Attempt at a Solution

I calculated the components of F1 and F2 with the following numbers:

I judged the angle of F1 to be (360 - 24 = 336).

F1: 21cos336 (x-component) + 21sin336 (y-component).

I judged the angle of F2 to be (90 - 24 = 66).

F2: 36cos66 (x-component) + 36sin66 (y-component).

I calculated the sum of these as 33.84i + 24.35j.

Judging by the picture, are my translations of the angles correct?

Any guidance is appreciated.
