Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.

Assume that the motor has accelerated the wheel up to an angular velocity wi with angular acceleration a in time t1. At this point, the motor is turned off and a
brake is applied that decelerates the wheel with a constant angular acceleration of -5a. Find t2, the time it will take the wheel to stop after the brake is
applied (that is, the time for the wheel to reach zero angular velocity)

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 has the cart (1.5 tons) starting at the final peak with a height of 140 metres (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 section is completely flat and is 393.7 feet long. The minimum time required for a ride to come to a stop safely is 6 seconds. a) What is the minimum height required for the ride to come to a stop safely? b) What is the power generated by the braking system of the ride?
