Amotorcyclist travels around a curved path that has a radius of 200 ft. while traveling around the curved path, the motorcyclist increases speed by 1.10 ft/s^2. 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 25.5 ft/s. part d - maximum constant speed of the motorcyclist. determine the maximum constant speed of the motorcyclist when the maxim um acceleration is 8.25 ft/s^2.
