Pierre conduit une voiture à vitesse constante sur une portion d’autoroute rectiligne. Il parcourt 450 m pendant une durée égale à 9500 ms. Puis, à la même vitesse, il aborde un virage en arc de cercle. 1. Calculer la vitesse de Pierre dans : a) Le référentiel lié à la voiture. b) Le référentiel lié à la route. 2. Quelle est la trajectoire de Pierre dans le référentiel lié à la route ? 3. En déduire la nature du mouvement de Pierre dans ce même référentiel.

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
