Bed: .61 m

Solving for his potential gravitational energy by using the equation Eg=mgh
Eg = .54(kg) x 9.8(m/s^2) x .61 (m)
Eg = 3.23 J
Potential Gravitaional Energy:
PEg = mgh
PEg= .54(kg) x 9.8(J) x .91(m)
PEg = 4.82 (J)
Final Velocity:
KE = PEg KE = .5 mv(f)^2
4.82(J) = .5 x .54(kg) x v^2
4.23(m/s^2) = v(f)
Minimum Force:
Ac = V^2 / R
V = Square root (9.8(m/s)^2 x .31 m)
V = 1.57(m/s)^2
Disproving: Everything in this scene is probable expect the fact that he is not going fast enough and the angle of the ramp is to low to reach the height of 10ft.
Energy of Loop:
PEg = mgh
PEg = .54(kg) x 9.8 x .31(m)
PEg = 1.64(J)
Law of Conservation:
KE - PE = KEf
4.82(J) - 1.64 (J) = KEf
3.18 (J) = KEf
Work Cited:
Force of Gravity:
Fg = mg Fg = 1.99(kg) x 9.8(m/s)^2
Fg = 19.5 N
On Car: 1.99(kg)
Gravity: (m/s)^2
Air Mass: .71(kg)
Hieght: 25(m)
Force of Gravity in Air:
Fg = mgh Fg = .71(kg) x 9.8(m/s)^2 x 25(m)
Fg = 173.95(N)
Disproved: The scene as a whole is very reckless and seems unreal yet, the facts check out mainly. Two things that are bad physics are the gliding ability and speed that buzz and woody have.
