A 50 kg teenager just got his license and is driving his brandnew Escalade (mass 1100 kg) at 30 m/s. As he is texting anddriving, he crashes into a stopped minivan, which has a mass of 980kg. Since he is not wearing a seatbelt, he flies out of the windowafter the crash. If the Escalade and Minivan move together with aspeed of 13 m/s after the perfectly elastic crash, with whatvelocity is the teenage (former) driver now flying through theair?
