A pickup truck weighing 4500 kg travels at a contact speed of 40 m/s around a circular track . The diameter of the circular track is 100 m. What is the magnitude of the acceleration of the truck ? If the acceleration is reduced to 40% keeping the mass and speed of the truck constant how much will be the new radius ?
