A motorcyclist travels around a curved path that has a r radius of 375ft. While travelling around the curved path, the motorcyclist increases speed by 1.10 ft/s2. If the motorcyclist starts from rest, 1. Determine the time needed to reach an acceleration of 4.75 ft/s2. Express your answer to three significant figures and include the appropriate units.
2. Determine the speed of the motorcyclist at the instant the acceleration is 6.25 ft/s2. Express your answer to three significant figures and include the appropriate units.
3. Determine the magnitude of the acceleration at the instant the speed of the motorcyclist is 26.5 ft/s. Express your answer to three significant figures and include the appropriate units.
4. Determine the maximum constant speed of the motorcyclist when the maximum acceleration is 6.25 ft/s2. Express your answer to three significant figures and include the appropriate units.
