[Free] A 3 kg chunk of putty moving at a speed of 5 m/s collides with and sticks to a 5 kg bowling ball that is initially at rest. What is their final velocity? Please explain. I am really confused. I know you have to use the conservation of momentum equation: \[ v_f = \frac{m_1 \cdot v_1}{m_1 + m_2} \] where: - \( m_1 \) is the mass of the putty, - \( v_1 \) is the velocity of the putty, - \( m_2 \) is the mass of the bowling ball, - \( v_f \) is the final velocity after collision. Please help!
