41. There is no acceleration in the x-direction (horizontal) so there is nothing to speed or slow down Harry left to right. He will travel the same speed as the helicopter when he falls out and that speed won't change until he lands in the pool. You can use the constant velocity equation (v=d/t) to solve for the displacement since you know the velocity (100 m/s) and the time it has to fall (2 seconds).
44. This is just like the problem at the end of the Guided Reading. If the ball falls from 20 m above the ground you can use d=1/2 gt^2 to solve for the time it takes to fall that far. If the ball has that long to travel 60 meters horizontally you can solve for how fast it must have traveled.
45. This is solved the same way as #44.

37, 41 and 47 are conceptual. You can use GUESS on #47 to prove it but you don't have to.
49. Since the athlete jumps up to and falls from that height you can use the equation d=1/2 gt^2 to solve for the time it takes them to fall 0.75 meter. Think about that time and the fact that the athlete jumps up and falls down.
October 13th, 2014 Problem at the end of Guided Reading: Projectiles
Remember that the horizontal direction is completely independent of the vertical direction. The ball acts like it was dropped regardless of the fact that it is moving horizontally.
2. Ignore the fact that the ball is thrown sideways (horizontally) and solve for the time it would take to fall that far (1 s)
3. If the ball is moving for 1 second before it hits the ground, and you know that it covers 20 m you can use the constant velocity equation (v=d/t) to solve for the velocity (20 m/s).
October 1st, 2014 Straight up Straight Down worksheet
You're filling in two parts of the speedometer on the right side of the worksheet. Using the acceleration equation (vf=vi+at) solve for how fast the rock would be going after each second of free fall. Hint, you know it should be getting faster every second its falling. You can mark this speed by drawing an arrow on the dial. Then you use the displacement equation to solve for how far it has fallen (which should also be increasing every second).
Questions #1-6 are based on the speedometers and odometers you filled in.

October 1st, 2014 "I'm Free Fallin'!" Worksheet #5-7
Use your the displacement equation that has been rearranged to be equal to time. Don't forget to make the displacements negative.
5. >0.5 seconds
6. <5 seconds
7. <0.5 seconds
September 30th, 2014 "I'm Free Fallin'!" Worksheet #1-4
Don't forget to make the displacements negative.
1. You know that gravity is pulling this camera down for 15 seconds. Use the displacement equation, don't forget to square the time! (>1000 meters)
2. Same set-up as #1 but its falling for less time, therefore its not going to travel as far. (20 meters)
3. Since the time is so much longer, the displacement is much larger than the previous questions. (>15,000 meters)
4. (>40 meters)
