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

find the relationship between the 2 particles' accelerations.

2. Relevant equations

m1=20kg

m2=40kg

wheel doesn't weigh but can move.

both particles move with friction.

μs=μk=0.2

F(t)=98e^{0.1t}

3. The attempt at a solution

I came up with 3 equations:

F(t)-fk_{1}-T_{1}=m_{1}a_{1}

T_{1}=2T_{2}

T_{2}-fk_{2}=m_{2}a_{2}

Why is the acceleration equation

a_{2}=2a_{1}?
