Homework Statement
Two containers are connected by a cord (of negligible mass) passing over a frictionless pulley (also of negligible mass). At time t = 0 container 1 has mass 1.3 kg and container 2 has mass 2.8 kg, but container 1 is losing mass (through a leak) at the constant rate of 0.200 kg/s. At what rate is the acceleration magnitude of the containers changing at (a)t = 0 and (b)t = 3 s? (c) When does the acceleration reach its maximum value?
Homework Equations
T - m1 g= m1 a
T - m2 g= -m2 a
a= m2 - m1 g/ m2 + m1
3. Attempt to solve the problem:
I have been trying to solve this problem, but I can get the same answer as the book.
The answer in the the book is:
a)0.653m/s3
b)0.896m/s3
c)6.50s
a=[m2-m1/m2+m1]g
da/dt = -[(2.8-m1)/(2.8+m1)^2](dm1/dt)g
after this, i don't know what to do anymore. Am i doing it right?Thanks! :)
