While traveling along at 96 km/h, a 14.4-kN auto runs out of gas 16 km from a service station. Neglecting friction, if the station is on a level 15.4 m above the elevation where the car stalled, how fast will the car be going when it rolls into the station, if in fact it gets there?

Question

Erk. FBDs and situational diagrams help.

anonymous · Answer

thanks for your reply but i kind of tried that already and i dont think it helped very much

nottim · Answer

I think the FBD would. Cause there's gravity. And at first, I wouldn't have noticed.

anonymous · Answer
