Physics is the study of matter and energy. Physics is also the study of how matter and energy interact.
Ah hah ! We can do this the easy way, or we can do it the hard way.
Whereas, in honor of, and pursuant to my natural laziness, I'm going to
do it the easy way, and not even talk about the hard way. Please fasten
your seat belt. It may be a boompy ride.
There are a few different ways to calculate the CHANGE in
an object's momentum. For this particular problem, it's
best to use this equation for "Change in momentum":
CHANGE in momentum = IMPULSE delivered to the object.
Do you remember how to calculate impulse ?
Impulse = (force exerted in the object) x (time the force lasts)
-- In the question, it says that the same force is exerted on each car,
and they all get it for 10 seconds apiece.
-- Since the force is the same on each car, and the force lasts for
the same amount of time on each car, the IMPULSE delivered to
each car is the same !
-- So the CHANGE IN MOMENTUM is the same for each car.
-- They all started out from 'rest', so each one started with zero momentum.
-- The CHANGE IN MOMENTUM is the same for each car.
-- So at the end of 10 seconds, NO CAR has the 'most momentum'.
All three cars have the SAME momentum.
Do you see why I said that this is the 'easy way' to solve it ?
Answer:
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Deposition means that all the sediments, soil, and rocks are all compressed (tightly pressed into each other) and create sedimentary rocks.
I hope this helps! :)
