Question

In an amusement park ride, a car of mass 930 kg travels along a track and through the dip shown. The velocity of the car initially is Vi = 4.4 m/s, the initial height above the dip is h1 = 1.4 m, and the final height above the dip is h2 = 0.4 m. Friction and air drag are negligible. What is the kinetic energy of the car after it reaches the far side of the dip at height h2. Give your answer in Joules to three significant digits. Do not include units in your answer.

Explanation / Answer

We generally do not answer the questions of those who are having low rating. You are having a rating of "45%". Please rate all answers and improve your rating. Even if you find the answers are incorrect, first rate Lifesaver or helpful to the best answer and then rate other answers as not helpful. But do rate them for the good of both of us. Thanks!! Coming to the problem Total energy = constant =>Initial K.E. + Initial P.E. = Final K.E. + Final P.E. =>(0.5*930*(4.4^2))+(930*9.81*1.4) = Final K.E. + (930*9.81*0.4) =>Final K.E. = 18125.70 J
