The first car has twice the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 12 m/s, they then have the same kinetic energy. a) What were the original speeds of the two cars?
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…

In this question, you are to solve the same problem using (a) the law of conservation of energy and energy conversions and (b) those famous 5 kinematics equations...here is the problem: Mr. Kambo has decided to pay the exorbitant amount of money it costs to fly to the moon – it has been on his bucket list forever!! Being allowed out of the space craft, Mr. Kambo goes exploring reaching a cliff 34.5 m high overlooking the landing area. He decides to jump off the cliff testing out the fact that the gravity on the moon is 1/6th of that on Earth. Calculate his speed of decent, just before he reaching the lunar surface.
