janae has an experiment where she is evaluating the data of her ramp experiment where she is asked to slide a tennis ball down a ramp with 5 different angles. Using the table down below Ramp angle in degrees Distance (in m) time 1 (s) time 2 (s) time 3 (s) T-avg Velocity(m/s) 20 1.7 0.8 0.7 0.9 0.8 2.125 m/s 30 1.5 0.9 1.1 1.0 1.0 1.5 m/s 45 2 1.2 1.3 1.4 1.4 1.54 m/s 60 1.8 1.5 1.6 1.7 1.7 1.125 m/s 70 1.9 1.6 1.8 2.0 2.0 1.06 m/s The variables can be used to express Gravitational Potential Energy: (Egp) and Kinetic Energy: (Ek) mathematically as shown below: For the object rolling down the ramp as shown in the drawing down below, what type of energy is present at point (1)? Explain. Point 2 is in the middle between 1 and 3. What type of energy is present at point (3)? Explain. Assuming that energy is conserved, you can develop an equation for the speed of the object at point (3) (i.e. v3). Since energy is conserved, write down “E1 = E3”. Plug in the appropriate energy equations for E1 and E3 using appropriate subscripts (i.e. h1, v3, etc). Solve the equation you just developed for v3. Does your equation for v3 agree with the results from the ramp experiments? Reference your data in the explanation. For each object: Calculate the potential energy and kinetic energy in the three points: 1, 2 and 3. Also find the speed of the object in the three point

Assuming that energy is conserved, you can develop an equation for the speed of the object at point (3) (i.e. v3).
Since energy is conserved, write down “E1 = E3”.
