Question 3: Write the Newton's Second Law equations for each of the two
masses from Question 2.
Mass A:
F(A) = m_A x g
F_k = m_A x g
F_\mu = \mu x m_A x g
T
Note: E_g and
F_k are
opposite to
each other so
E_{net}(A) = T - F_k they cancel.
= T - (\mu x m_A x g)
Mass B:
F_g(B) = m_B x g
T
E_{net}(B) = T - (m_B x g)
Question 4:
Part A) Solve the equation from Question 3 for the tension in the string for
the falling mass (coin B). Expression only, NO NUMBERS.

Question 3: Write the Newton's Second Law equations for each of the two
masses from Question 2.
Mass A:
F(A) = mA x g
Fk = mA x g
Fμ= μx mA x g
T
Note: Eg and
Fk are
opposite to
each other so
Enet(A) = T - Fk they cancel.
= T - (μx mA x g)
Mass B:
Fg(B) = mB x g
T
Enet(B) = T - (mB x g)
Question 4:
Part A) Solve the equation from Question 3 for the tension in the string for
the falling mass (coin B). Expression only, NO NUMBERS.
msys = System mass = mA + mB
