A carnival ferris wheel completes five turns about its horizontal axis every minute. What is the acceleration of a passenger at his/ her lowest point on the ride? I understand that 1/f= T which is how you find the period and that minutes must be converted to sec, but I'm ...

The velocity time graph is a straight line passing through the origin with a slope of 3.3 m/s². From the graph, it should be possible to read off time, t, it takes to reach 88 m/s. From the equation of kinematics, calculate S, the distance travelled over the time ...
