A student standing on a stationary skateboard tosses a textbook with a mass of m1,-1.4 kg to a friend standing in front of him. The student and the skateboard have a combined mass of me-91 kg and the book leaves his hand at a velocity of vb = 2.42 m/s at an angle of 24° with respect to the horizontal Randomized Variables mb 14 kg mc 91 kg Vh 2.42 m/s 33% Part (a) Write an expression for the magnitude of the velocity of the student, vs, after throwing the book Grade Summary Deductions Potential Late work % 82% Late Potential 82% 0% cos(α) sin(α) cos(φ) sin(φ) cos(0) sin(0) Submissions Attempts remaining: 8 (4% per attempt) detailed view 1 2 3 0 0 Submit Hint I give up!
