Blocks with masses of 1.0 kg, 2.0 kg, and 3.0 kg are lined up in a row on a frictionless table. all three are pushed forward by a 17 n force applied to the 1.0 kg block.

part a:
how much force does the 2.0 kg block exert on the 3.0 kg block?

part b
how much force does the 2.0 kg block exert on the 1.0 kg block?

The 2.0 kg block exert 8.5 Newton on the 3.0 kg block

The 2.0 kg block exert 14¹/₆ Newton on the 1.0 kg block

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

We will use Newton's 2nd law formula for this problem.

The force acting on the 3.0 kg block could be calculated as follows:

The force acting on the 1.0 kg block could be calculated as follows:

Grade: High School

Subject: Physics

Chapter: Dynamics

Keywords: Gravity , Unit , Magnitude , Attraction , Distance , Mass , Newton , Law , Gravitational , Constant

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
