Two identical springs with spring constant 50 N/m support a 5.0-N weight as in the picture below. What is the tension in spring A?
 
 
 
   
  a.
  1.45 N
   
  b.
  2.50 N
   
  c.
  2.89 N
   
  d.
  3.75 N
   
  e.
  5.00 N

Question 2

In the figure, the coefficient of kinetic friction between the surface and the larger block is 0.20, and the coefficient of kinetic friction between the surface and the smaller block is 0.30. If F = 10 N and M = 1.0 kg, what is the tension in the connecting string?
 
   


   
  a.
  8.0 N
   
  b.
  6.0 N
   
  c.
