The book that weighs less
Moving the balls closer together pumping more air into the soccer ball putting the baseball in a plastic case
Measure the length of one side and then cube the answer. So if x represents the measurement of one side, x³ will give you the volume.
"Multiple accelerations" is a puzzling phrase, and I'd be curious to understand it
better. Sadly however, you haven't explained it at all.
If the multiple accelerations are the accelerations of multiple objects, then
the net force on each object is the product of (its mass) x (its acceleration).
If the multiple accelerations are the acceleration of one object at different times,
then at any instant of time, the net force on the object is the product of (its mass) x
(its acceleration at that instant).

The speed of the cart changed because it stopped.
Hope I could help!
