A test car starts from rest on a horizontal circular track of 120-m radius and increases its speed at a uniform rate to reach 130 km/h in 15 seconds. Determine the magnitude a of the total acceleration of the car 10 seconds after the start. (a = 5.40 m/s²) r ν 12 Consider Problem 1. If the car starts from rest and increases its speed at a time-varying rate of 0.6√t m/s², where t is the time in seconds, determine the total acceleration of the car after one revolution.
