Rube Goldberg Project
Calculation 1
Velocity of a Kinect Ball on a Track
Formula: V = d/t
Distance = 0.46 meters
Time = 1.45 sec
V= .46 meters/ 1.45sec
Velocity = 0.317 m/s
Calculation 2
Kinetic Energy of Marble on Ramp
Formula: KE=1/2m
Velocity of Marble = 0.36m/s
KE=1/2 (.00546 kg) (0.36 m/s
KE= 0.00036 J
Calculation 3
Momentum of Swinging Hammer
P=M*V
Velocity of Hammer = 13.66m/s
P=(0.1325kg)(13.66m/s)
P=1.809 kg*m/
Calculation 4
Hang Time of Marble in Tube
Formula: T= d/(0.5*9.8)
Distance = .09meters
T= .09meters/(0.5*9.8)
T=2.33s
Calculation 5
Conservation of Momentum Between Marbles
Formula: M₁V₁= M₂V₂
Mass of Marble = 0.00534kg
Velocity of Marble₁ = .0033m/s
(0.00546kg)(.0033m/s)=(0.00534kg)(V₂)
V₂ =.0023m/s
Calculation 6
Calculating the Velocity of a Roller-coaster from Video
Formula: V=d/t
Distance = 0.005 meters
Time/Frame Rate = 0.04 sec
V=(.005sec)(.04meters)
Velocity=.0002m/s
Calculation 7
Mechanical Advantage Incline Planes on the Green Track.
Formula: MA=(dv/dr)m
Length of Track= .48meters
Height of Track= .6meters
Weight of Ball = 0.01861kg
MA=(6cm/48cm)0.01861kg
MA=0.002326kg
Calculation 8
Potential Energy of Falling Marble in Tube
Formula: PE=mgh
Mass of Marble = 0.00484kg
Height = 0.115 meters
PE=(0.00484kg)(9.8m/ )(0.115meters)
PE=0.005454J

Rocket Project
Rocket Log
Day 1 Entry 1- Today we figured out what our rocket will look like. We decided to do the kilo lift.
Day 2 Entry 2- Today we will glue 6 bottles together. 1 hour later- We forgot to sand! We are SOOOO dead!
Day 5 Entry 3- Today is a launch day. Launch the big guy! 1 hour later- The big guy is blown in half. Fixing at lunch.
Day 6 Entry 4- Glueing a second rocket to be safe. We need a tip and a parachute.
Day 7 Entry 5- Second rocket blown out, I trashed it.
Night 10 Entry 6- Mitchell worked on a parachute, he reinforced it, it should hold a kilo up. Also glued on new nozzle and tip. The kilo is more enforced and padded.
Day 11 Entry 7- Worked on our parachute and made up the name.
Day 12 Entry 8- Used hot glue and attached fins and painted it. We are ready for launch day!
