8 The Spring Scale In The Diagram Below Reads 10 5 N If The Cart Moves Toward T

#8. The spring scale in the diagram below reads 10.5 N. If the cart moves toward the right with an acceleration also towards the right of 3.25 m/s2,what is the mass of the cart? (Answer: 3.23 kg) #9. The force applied to the cart in previous Question by spring scale FA is still 10.5 N. The cart now moves toward the right with a constant velocity. What is the magnitude the frictional force? (Answer: 10.5 N)#10. What is the direction of frictional force? (Answer: To the left)#11. The force applied to the cart in the above Question by spring scale FA is still 10.5 N. The cart now moves toward the right with an acceleration also toward the right of 1.75 m/s^2. What is the magnitude of friction force?
