1. A new directive from the NCSSM administration has ordered the Physics Instructors to fire t-shirts out of tshirt cannons at students to reward them whenever they get the right answer in class; students are, of course, also required to wear roller skates. A 156 g t-shirt can be fired from a t-shirt cannon at 53.5 m/s. A 73 kg student has won their rst t-shirt. Overjoyed, they run/skate toward their instructor at 1.85 m/s when the t-shirt cannon is fired. If the student catches the t-shirt and clings tightly to it, what will the magnitude and direction of their velocity be as they skate away
