Question
Please answer the questions below using the diagram above:
1.) The mass of the cart is 3.0kg. Now two forces are applied to the cart with two different spring scales as shown below. The spring scale FA reads 10.5N.The cart now moves toward the left with an acceleration toward the left of 2.50m/s2. What does spring scale FB read?

1).
Fb - Fa = ma
=> Fb -10.5 = 3*2.5
=> Fb = 18 N
2).
Fa - Fb = ma
=> 10.5 -Fb = 3*2.5
=> Fb = 3 N
3).
Fa - Fb = ma
=> 10.5 -Fb = 3*5.5
=> Fb = -6 N
