1. WATERFALL BY: MISAKI A., TERESA C., EMILY L., SELINA M.

2.  Length of the ride: 1.2 KM  Time of ride: 1.42 min  Height of drop: 12.19 m INFO

3.  What is the velocity of the log before it it’s the water? PART A

4.  What is the deceleration after the log ride hits the water? (it takes 4.5m to slow down to 3m/s) PART B

5.  What is the force of the water? (m-212kg) PART C

6.  Find the average velocity of the ride. (m/s) PART D 1

7.  Find the average speed of the ride. (m/s) PART D 2

9.  PE1+KE1=PE2+KE2 mg(12.19)=1/2mv2 12.19(9.8)=1/2v2 238.924=v2 15.5m/s=v Velocity is 15.5 m/s ANSWER A

10.  V2=v2+2ad (3.0)2=(15.5)2+2a(4.5) 9=240.25+9a a=-25.694m/s2 a=-26m/s2 ANSWER B

11. F=ma F=(212)(25.694) F=5447.2 N Fwater= 545oN ANSWER C

12.  V=d/t d = 0 because it starts and finish at the same point T=1.42 min -> 201 s V=0/201 Average velocity = 0m/s ANSWER D1

13. V=d/t d= 1.2km -> 12.00m T= 1.42min -> 201s V=1200/201 Average speed = 6.0 m/s ANSWER Q D2
