6. The figure shows a student pushing a 1.22 kg box across a frictionless floor a distance of 5.0 m by applying a force of 30.0 N.
What is the work done on the box by the two forces, Fn and Fa , as it
is pushed 5.0 m along the floor?
F = 12.0 N
F=30.0 N
5 m
A. Work by Fn = 0 Joules Work by Fa = 0 Joules
B. Work by Fn = 0 Joules Work by Fa = 150 Joules
C. Work by Fn = 60 Joules Work by Fa = 0 Joules
D. Work by Fn = 60 Joules Work by Fa = 150 Joules
