What should the FBD for m2 look like?

Answer explanation

The tension force arrow should be the SAME length to represent the same magnitude of tension.

The force due to gravity can be shorter to represent the assumption that m2 < m1

What should the net force be?

• F_net = (-)m_1g+m_2g

• F_net = m_1g+m_2g

• F_net = (-)m_1g-m_2g

• F_net = m_1g+m_2g-T

What's the net force?

• F_net = m_2g+ (-)F_f

• F_net = m_2g+ F_f

• F_net = 0
