Question

look at the diagram below.
answer the following two questions.
is the object moving?
what direction is the object moving?
a left
b not moving
c moving
d right

Explanation:

Step1: Calculate the net force

The net force \(F_{net}\) is calculated by subtracting the smaller force from the larger force. Here, \(F_1 = 8.0\space N\) (left - ward) and \(F_2=2.0\space N\) (right - ward). Since the forces are in opposite directions, \(F_{net}=F_1 - F_2\).
\(F_{net}=8.0 - 2.0=6.0\space N\) (left - ward)

Step2: Determine the motion

According to Newton's second law \(F = ma\) (where \(m = 2.0\space kg\) and \(F=F_{net}\)). Since \(F_{net}
eq0\), the acceleration \(a=\frac{F_{net}}{m}
eq0\). A non - zero acceleration means the object is moving. The direction of the net force (and thus the direction of acceleration and the direction of motion, assuming initial velocity is zero or in the direction of the net force) is the direction of the larger force.

Answer:

C. Moving, A. Left
