3. In this question you will do some algebra to determine two relations that you will need for Part 2 of this lab. Write down Eq. 11 twice. In the first statement, set the rotational kinetic energy term equal to zero (i.e. lw? = 0) –- call this your "No Krot model". Leave the second as it is written in Eq. 11– call this your "Krot model". For both models, solve for v in terms of g, h, and a. In the Krot model, you will need to use I (Eq. 3) and w = KMR2 /r. The solution for the Krot model will have a k term as well. Once you have solved for v, use the kinematic relation, v = and the trigonometric relationship, h both models separately. at, = L sin 0, solve for t for NOTE: L is the length of the incline plane. NOTE: a is different for the two models (refer to the "Rotational Mechanics" discussion in the introduction): In the "No Kpot model", a = g sin 0 (remember the Newton's 2nd Law lab) In the "Krot model", a is given by equation 8 These two solutions represent the predicted time it…
