1. Week 10s: Kinetic Data Interpretation Worked Jump Height Calculation Dr. Andrew Greene

2. Vertical Velocity TO
vf (vt-o) = ? vi (vt-d ) = m·s-1 a = ? s = ? t = 0.56 seconds Mass = 88 kg Total Impulse = 763 N.s BW Impulse = N.s Jump Impulse = N.s Which Calculation do you select? Calculate the Vt-d (Vf)
a = ?
Vf = ?
Vi = m·s-1
Jump Impulse
Impulse BW BW
0.56 seconds

3. Vertical Velocity TO
Jump Impulse =  m x v Jump Impulse = m x vt-o – m x vt-d

4. Vertical Velocity TO
Jump Impulse =  m x v =  m x v = m x vt-o – m x vt-d = (88 x vt-o) – (88 x -2.18) = 88 x (vt-o – -2.18) = vt-o 88 vt-o = 3.16 m·s-1

5. Maximum Jump Height vi (vt-o) = 3.16 m·s-1 a = -9.806 m·s-2 s = ?
vf = 0 m·s-1
vi (vt-o) = 3.16 m·s-1
a = m·s-2
s = ?
t = ?
Which Calculation do you select?
Calculate the Vt-d (Vf)
Vf = 0 m·s-1
s = ?
vi (vt-o) = 3.16 m·s-1

6. Maximum Jump Height
vf2 = vi2 + 2.a.s vf = 0 m·s-1 vi (vt-o) = 3.16 m·s-1 a = m·s-2 s = ?
a = m·s-2
s = ?
vi (vt-o) =3.16 m·s-1
Vf = 0 m·s-1

7. Maximum Jump Height
vf2 = vi2 + 2.a.s 02 = (2 x x s)

8. Maximum Jump Height
vf2 = vi2 + 2.a.s 02 = (2 x x s) 0 = ( x s) 0 – 9.99 = x s = x s = s s = 0.51 m (51cm)
