Problem

Two blocks

A

and

B

of masses

2\,\text{kg}

and

3\,\text{kg}

respectively are kept in contact on a horizontal frictionless surface. A horizontal force of

15\,\text{N}

is applied on block

A

toward block

B

. a. (i) Isolate each block and sketch its free-body diagram, clearly labeling all external forces. b. (ii) Using the diagrams, write the equations of motion for each block along the horizontal direction. c. (iii) Calculate (a) the common acceleration of the system and (b) the magnitude of the force that block

B

exerts on block

A
