Question

Three blocks, each of mass 13 kg are on a frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 1.4 m/s2.

1. What is the magnitude of the force on block A from the hand? 54.6 N

2. What is the net horizontal force on block A ? 18.2 N

3. What is the horizontal force on block A due to block B? -36.4 N

4. What is the net horizontal force on block B? 18.2 N

5. What is the horizontal force on block B due to block C?

Explanation / Answer

5)

Cleary force on block C is due to Block B is 18.2 N

so According to Newton's third law

Force on block B due to block C is -18.2 N <<<<<----Answer
