A student standing on a stationary skateboard tosses a textbook with a mass of mb = 1.2 kg to a friend standing in front of him. The student and the skateboard have a combined mass of mc = 81 kg and the book leaves his hand at a velocity of vb = 4.71 m/s at an angle of 29° with respect to the horizontal. a)Calculate the magnitude of the velocity of the student, vs, in meters per second. b)What is the magnitude of the momentum, pe, which was transferred from the skateboard to the the Earth during the time the book is being thrown (in kilogram meters per second)?
