d = v0t + ½ 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

6. SEESAW: PART ONE
1975.71 = V0(1.36) + ½ (-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

7. SEESAW: PART TWO
Scale factor: Coyote shown on the screen : Coyote’s
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

8. 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 °
