A student standing on a stationary skateboard tosses a textbook with a mass of mb = 1.25 kg to a friend standing in front of him. The student and the skateboard have a combined mass of mc = 82 kg and the book leaves his hand at a velocity of 2.8 m/s at an angle of 43° with respect to the horizontal.

Write an expression for the magnitude of the velocity of the student, vs, after throwing the book.

Calculate for the magnitude of the velocity of the student, vs in m/s?

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 kg-m/s)?
