Suppose two children push horizontally, but in exactly opposite directions, on a wagon containing a third child. The first child exerts a force of
F1
= 75.0 N, the second a force of
F2
= 95.0 N, friction is 12.0 N, and the mass of the third child plus wagon is 30.0 kg.
(a)
What is the system of interest if the acceleration of the child in the wagon is to be calculated? (Select all that apply.)
the wagon
the child in the wagon
the children outside the wagon
(b)
Which of the following diagrams correctly represents the free body diagram for the situation described here? Calculate the acceleration (in m/s2).
m/s2
(d)
What would the acceleration (in m/s2) be if friction is 20.0 N?
m/s2.
