- Homework Statement
- 1. Place a ramp on the table to that its bottom portion is flush with the edge of the table.
Measure the vertical height of the ramp using the table as a reference.
2. Measure the mass of the marble.
3. Use the info gathered so far to establish the initial potential energy.
4. Devise a method making use of the carbon paper and your knowledge of projectile
motion to determine the velocity that the marble leaves the ramp. Ask yourself why
you would need to know this.
- Relevant Equations
- Potential and Kinetic Energy Formulas
Ek = (mv^2)/2
Ep = mgh
Kinematics Equations
D = [(v1+v2)/2]T
D = v1T + 0.5v1T^2
D = v2T - 0.5v2T^2
v2^2 = v1^2 + 2aD
v2 = v1 + aT
m = mass
g = gravity
h = height
v = velocity
v1 = initial velocity
v2 = terminal velocity
a = acceleration
D = displacement
T = time
I understand the basic way of doing it if no energy was lost, but because it is and it adds this whole component of projectile motion I'm feeling a bit lost. At first I wanted to time how long it took from the top of the ramp to when it hit the ground, but I couldn't figure out a way of making it work and also thought it might be against the rules as it wants to use the carbon paper. So using the carbon paper you get to know the horizontal displacement, but I'm not sure what else. You also know the vertical displacement is the height of the table and the vertical acceleration is gravity. Hoping someone could point out a hint maybe or something I'm missing or not understanding, thank you!
