To analyze the motion of a body that is traveling along a curved path, to determine the body's acceleration, velocity, and position. A motorcyclist travels around a curved path that has a radius of 475 ft . While traveling around the curved path, the motorcyclist increases speed by 1.00 ft/s^2. Part A - Finding the time interval for the motorcyclist to reach a given acceleration If the motorcyclist starts from rest, determine the time needed to reach an acceleration of 5.75. ft/s^2 Express your answer to two significant figures and include the appropriate units Part B - Speed of the Motorcyclist at a Given Acceleration Determine the speed of the motorcyclist at the instant the acceleration is 7.5 ft/s^2. Express your answer to two significant figures and include the appropriate units. Part C - Magnitude of the Motorcyclist's Acceleration at a Given Speed Determine the magnitude of the acceleration at the instant the speed of the motorcyclist is 25 ft/s . Express your answer to two significant figures and include the appropriate units. Part D - Maximum Constant Speed of the Motorcyclist Determine the maximum constant speed of the motorcyclist when the maximum acceleration is 7.5 ft/s^2.
