A 30 kg student drops down from the monkey bars. The acceleration due to gravity is -9.8 m/s^2. Neglecting air drag, what is the net force acting the on student?
A)-294 N
B)-3 N
C)0.3 N
D)294 N

The net force on the student is A) -294 N

Explanation:

Neglecting air resistance, there is only one force acting on the student: the force of gravity, which is given by

[tex]F=mg[/tex]

where

m is the mass of the student

g is the acceleration of gravity

In this problem, we have:

m = 30 kg is the mass of the student

[tex]g=-9.8 m/s^2[/tex] is the acceleration of gravity, where the negative sign means the direction is downward

Substituting, we find the force of gravity on the student:

[tex]F=(30)(-9.8)=-294 N[/tex]

And since this is the only force acting on the student, it is also the net force on him.
