Homework 2 MECH 2021 Kinematics and Kinetics of Machines Summer 2025 3. A shell is moving near a wall and explodes into 3 pieces, with 3 different masses ($m_A$ = 9 kg, $m_B$ = 10 kg, $m_C$ = 12 kg). The masses all hit the wall at different times, $t_A$ = 0.35 s, $t_B$ = 0.12 s, $t_C$ = 0.842 s. Determine the initial velocity of the shell. ($\vec{v_0} \sim 10\hat{i} + 10\hat{j} - 20\hat{k}$)
