d) all of the above
An accelerating car
a) has an unbalanced for acting on it
b) has balanced forces acting on it.

Two books are laying on a table top. With out picking them up how could you determine which has the greatest inertia
a) look at them the larger one will have more inertia
b) neither one has inertia they are not moving
c) it is impossible to tell
d) give each one a push, the one that moves the easiest has less mass thus less inertia
