1a. A car drives around a circular track of diameter 154 m at a constant speed of 45.1 m/s. During the time it takes the car to travel 97 degrees around, what is the magnitude of the car s average acceleration? b. A car starts from rest, then accelerates at a constant rate over a distance of 63 m. It then immediately decelerates at a constant rate over a distance of 122 m. The entire trip lasts a total duration...

4. A car of mass m is traveling with constant speed v around a circular banked road of radius R, see the side view and the free-body diagram. a) Apply Newton’s 2nd law to the car, i.e. write equations for the centripetal, angular, and vertical components of the net force. b) Determine the angle θ at which the road should be banked so that no static friction is required to drive the car. Now, include the static friction force FS...

Charlie and Alexandra are running around a circular track with radius 60 meters. Charlie started at the westernmost point of the track, and, at the same time, Alexandra started at the northernmost point. They both run counterclockwise. Alexandra runs at 4 meters per second, and will take exactly 3 minutes to catch up to Charlie. Impose a coordinate system with units in meters where the origin is at the center of the circular track, and give the x- and y-coordinates...
