As a freshly graduated student from WCCI, you are aiming to become a safety engineer for Bolliger and Mabillard (B&M) so that you can help create rollercoasters for Canada's Wonderland. For many roller coasters, it is important that the rides do not come to a complete stop abruptly at the end of a ride (or else bones will break!). The final section of the rollercoaster hasthe cart (1.5 tons) strtaing at the final peak with a height of 140 m(assume the cart starts at rest.) The final section(3-4)of the ride is designed to come to a stop using a material with a coefficient of friction of 0.668. The final is completely flat and is 393.7 feet long.The minimum time requiredfor a ride to come to a stop safely is 6 seconds.
