3. THE FALL d = v0t + at2 d = -4.9 (20.08)2 = -1975.71m 2.0 x 103m v2 = v0 2 + 2ad = 2(-9.8)(-1975.71) = 196.78 m/s 2.0 x 102m/s Time 1 Time 2 Time 3 Time Average First Fall (case #1) 20.50 19.90 19.86 20.08

4. SEESAW: PART ONE Time 1 Time 2 Time 3 Time Average Up (case #2) 0.73 0.83 0.76 0.77 d = v0t + at2 1975.71 = V0(0.77) 4.9 (0.77) 2 V0 = 2569.63 m/s 2600 m/s vf = v0 + at vf = 2569.63 + (-9.8)(0.77) vf = 2562.084m/s 2600 m/s

5. SEESAW: PART ONE 1975.71 = V0(1.36) + (-9.8) 1.562 1975.71 = V0(1.36) 4.9(1.8496) v0 = 1984.16304/1.36 = 1458.94 v2 = (1458.94)2 + 2(-9.8)(-1975.71) vf = 1472.15 m/s 1500 m/s

6. SEESAW: PART TWO Scale factor: Coyote shown on the screen : Coyotes actual length in real life (1), Boulder shown on the screen : Length of the boulder in real life (2) 1. 2cm : 58 cm 2. 18 cm : 522cm or 5.22 m

7. SEESAW: PART TWO range = vx x Ttotal 5.22m = vx X 0.80 seconds vx = 6.525m/s = V0cos60 V0 = 13.05m/s, which is approximately 13 m/s. v0x = v0cos60 v0y = v0sin60
