A student standing on a stationary skateboard tosses a textbook with a mass of mb = 1.55 kg to a friend standing in front of him. The student and the skateboard have a combined mass of mc = 127 kg and the book leaves his hand at a velocity of 3.6 m/s at an angle of 33° with respect to the horizontal.
Part (a) Write an expression for the magnitude of the velocity of the student, vs, after throwing the book.
Part (b) Solve for the magnitude of the velocity of the student, vs in m/s?
