Question:
A physics student driving a \(1200-\mathrm{kg}\) car runs into the rear of a \(2000-\mathrm{kg}\) car stopped at a red light. From the fact that the joined vehicles skidded forward \(4.0 \mathrm{~m}\), the investigating police officer calculates that the speed after the collision was \(6.6 \mathrm{~m} / \mathrm{s}\). Based on this information, calculate the student's speed before impact.
