Atwood’s Machine Worksheet
W = mg
F = ma
Instructions: Solve each problem taking into account the forces present and how they
affect the apparatus.
1. Two weights (m1 = 1.2kg and m2 = 2.9kg) are
suspended as shown. When the machine is released, the
weights move and accelerate together
a. What are the weights of m1 and m2?
m2
b. Draw a FBD for each of the weights
m1
c. What is the net force acting on the system?
d. What is the acceleration of the system?

Complex Force Problem Worksheet
W = mg
F = ma
Ff = µ N
Instructions: Solve each problem considering all the forces present.
1. A hanging weight (m = 2.5kg) is
connected to a block (m = 4.0kg) via a
pulley as shown. Once released, the block
experiences a force of friction of 7N.
a. What is the weight of the hanging
weight?
b. Draw a FBD for the block.
c. Draw a FBD for the hanging weight.
d. What is the net force acting on the system?
e. What is the acceleration of the system?
