Question

Blocks with masses of 2.0 kg, 3.0 kg, and 4.0 kgare lined up in a row on a frictionless table. All three are pushed forward by a 13 N force applied to the 2.0 kg block.

Part A

How much force does the 3.0 kg block exert on the 4.0 kg block?

Express your answer to two significant figures and include the appropriate units.

Part B

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

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Part A)

m1=2Kg; m2= 3Kg; m3=4Kg ; F=13N;

m= 2+3+4= 9Kg

F=m.a

13= 9.a

a=1.4444m/s2

Force exerted by 3Kg block on 6Kg block

F= 6*1.444=8.664N

Part b)

Force exerted by 3Kg block on 2Kg block

F=2*1.4444= 2.888 m/s2
