A 1.4 kg rock with an initial velocity of 14 m/s collides with a 12 kg pumpkin sitting on someone's porch. The pumpkin slides across the porch with the rock embedded inside of it. Since the collision is inelastic, only momentum is conserved, but kinetic energy is not conserved. Use the conservation of momentum equation: Initial mass, . velocity + Initial mass, . velocity = Final mass . velocity What is the final velocity (m/s) of the combined mass just after the collision? Give your numerical answer to two decimal places
