A 400-Kg Box Sits Atop a 10

question 2

Multiple Choice

A 4.00-kg box sits atop a 10.0-kg box on a horizontal table.The coefficient of kinetic friction between the two boxes and between the lower box and the table is 0.600,while the coefficient of static friction between these same surfaces is 0.800.A horizontal pull to the right is exerted on the lower box,as shown in the figure,and the boxes move together.What is the friction force on the UPPER box?

• A) 19.3 N to the right
• B) 19.3 N to the left
• C) 23.5 N to the right
• D) 31.4 N to the right
• E) 31.4 N to the left
