Blocks with masses of 2.0 kg, 3.0 kg, and 4.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 20 N force applied to the 2.0 kg block. a) How much force does the 3.0 kg block exert on the 4.0 kg block?

b) How much force does the 3.0 kg block exert on the 2.0 kg block?

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

close lines strong magnet less close weaker
