It is the final seconds of an ice hockey game between the Flyers and the Bruins. The Bruins are down by 1 point. With 20 s left in the game, the Bruins pull the goalie and have him play as a forward in an attempt to tie the game. The Flyers successfully defend their goal for 9 s. With only 1.25 s remaining on the game clock, a Flyer shoots the puck on the ice past the skates and sticks of the other players and toward the Bruins goal. The puck is 37 m from the goal when it leaves the stick with an initial horizontal velocity of 30 m/s. The shot is perfectly directed toward the empty goal, but the ice slows the puck down at a constant rate of 0.50 m/s2 as it slides toward the goal. None of the Bruins can stop the puck before it reaches the goal.

12) Chapter 2, Problem 7 (1 pt) What equation is most appropriate for determining how far the puck can travel between when the Flyer shoots it and when the game clock reaches zero? i) ii) (1.5 pts) The answer to part (i) is the farthest from goal the Flyer can be if his shot is to score before the game clock reaches zero. All else being equal, which of the following changes would the allow the Flyer to shoot from farther from goal and still score before the clock reaches zero? a. (T/F) The Flyer shoots the puck with 1.4 s remaining on the game clock b. (T/F The puck leaves the stick with an initial horizontal velocity of 32 m/s c. (T/F) The ice slows the puck down at a constant rate of 0.7 m/s

6. Sean is running a 100 m dash. When the starter's pistol fires, he leaves the starting block and continues speeding up until 6 s into the race, when he reaches his top speed of 11 m/s. He holds this speed for 2 s; then his speed has slowed to 10 m/s by the time he crosses the finish line 11 s after he started the race.
