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)=98e0.1t 3. The attempt at a solution I came up with 3 equations: F(t)-fk1-T1=m1a1 T1=2T2 T2-fk2=m2a2 Why is the acceleration equation a2=2a1?
