A box moving to the right experiences four forces, as shown. Key
F = 10 N
F = Normal Force
F, = Friction Force
F Force due to Gravity
FA = Applied Force
F, = 15 N
F = 15 N
F = 10 N
If these forces are applied for a given time interval, t, which statement describes what the box will do during
that time?
A. The box will slow down during the time interval.
B. The box will maintain a constant velocity.
C. The box will speed up during the time interval.
D. The box will change direction but not speed.
