(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two people pull on a 25kg box that is resting on smooth ice. What is the acceleration of the box? Assume friction is negligible.

the img is important bc of the description of the two forces acting on the box. try and ignore my frustrated chicken scratch.

t1=50

t2=100

theta=45deg

2. Relevant equations

fnet= ma

3. The attempt at a solution

I tried to calculate the x and y acceleration using fnet=max and fnet=may but I got stuck. I wasn't sure based on the picture how to calculate gravity or the normal force so I just ignored it... possibly a mistake. i have

Fnet=max

t2x=max

t2cos(theta)=max

Fnet=may

t1+t2y=may

t1+t2sin(theta)=may

not sure where to go from here.
