Three blocks are in contact with each other
on a frictionless horizontal surface. A 696 N
horizontal force is applied to the block with
mass of 4.7 kg as shown in the ﬁgure below.
The acceleration of gravity is 9.8 m/s
4.7 kg 5.5 kg 7.1 kg
) What is the resultant force on the block
with mass 5.5 kg?
Answer in units of N
