Question

Part A Boxes A andB are in contact on frictionless surface, as shown in the following figure. Box A has mass 22.0 kg and box

Answer 1

Answer #1

Acceleration of the whole system is 'a'

F=(M_A+ M_B)a ...1

here F=100 N , M_A =22.0 kg , M_B =8.0kg

put these value in equation 1

100=(22+8)a

100=30 a

a=100/30

a=3.333 m/s²

so force exerts on the box B by A

f=M_B a

=8×3.333

f=26.664 N

f=27 N. Answer(in two significant figures)
