Document Summary
Phya10 practical week 7: you are in a small boat about a meter from a dock. Ordinarily you can jump a meter no problem, but your friend on the dock warns you not to try it. Explain using ideas about momentum: three identical balls slide on a table and hit a block that is xed to the table (see. In the gures we are looking down from above. In each case the ball is going at the same speed before it hits the block. Rank in order from the largest to the smallest the magnitude of the force exerted on the block by the ball. Explain your answer: estimate the maximum forces acting on a 100 kg person involved in a car crash if the car runs into a wall while traveling at 20 m/s. Choose the following three scenarios: 1) no seatbelt or air bag, so the person comes to a full stop in a total distance of about.
