17. A skateboard has a mass of 3.2 kg. If it slips out from a skateboarder and has
a velocity of 1.0 m/sex, what is the momentum of the skateboard?
18. You drop your physics textbook on your big toe. If the textbook has a mass of
m) = 2.18 kg. The book is in freefall, calculate the force when the book hits
your foot.
19. Suppose that you lift your foot and kind of catch the book. I say kind of catch
the book because as the book hits your foot, you slowly lower it to the
ground. Will your big toe hurt more or less than it did problem 18?
20. What was the change in momentum from problem 19 if it took half a second
for the book to come to rest?
