Question
The figure below shows two boxes connected to each other by a light cord that passes over a pulley with negligible friction. The box of mass 
m1 = 3.80 kg
 lies on a horizontal table with negligible friction, while the box of mass 
m2 = 10.3 kg
 hangs vertically.
Two boxes labeled m1 and m2 are attached together by a cord.
  • Box m1 lies on a horizontal table with the cord extending horizontally from its right side.
  • The cord extends horizontally from the right side of m1 then goes over a pulley and then straight down to m2.
  • Box m2 hangs from the cord.
(a)
What is the magnitude of the acceleration of each box (in m/s2)? (Here, 
a1
 is the acceleration of 
m1,
 and 
a2
 is the acceleration of 
m2.)
a1
= m/s2
a2
= m/s2
(b)
What is the tension in the cord (in N)?
 N
