10. A plate with a mass of 0.375 kg is dropped and has a speed of 3 m/s when it suddenly hits the hard kitchen floor. Calculate the change in momentum. (Note: the final speed of the plate is, of course, zero when it hits the floor.) 11. Consider the plate from the previous question. The floor provided an impact force that acted on the plate. It acted on the plate very suddenly-it was a mere fraction of a second. If the force acted on the plate for 0.00024 s, calculate the force of impact. Copyright 2009 by Jason Neil.

The force of impact is very large, thereby breaking the plate. If the time were larger than 0.00024 s, would the force of impact be larger or smaller than your answer to question 11.

14. Consider again the plate in questions 10 and 11. If the plate hits a pillow instead of the floor
it might not break. This question will examine the physics that explains why the plate may
not break.
