A test car starts from rest on a horizontal circular track of 65-m radius and increases its speed at a uniform rate to reach 80 km/h in 10 seconds. Determine the magnitude a of the total acceleration of the car 8 seconds after the start. Part 1 65 m Calculate the tangential component at of the acceleration. Answer: ati m/s²
