Problem:
A car is initially traveling along a horizontal circular path with radius of 400 ft at a velocity of 60 miles/hour (mph). When the driver further press the gas paddle, the speed of the car increases at a constant rate of 3 ft/s^2 .
Required:
Question 1: Determine the speed of the car when it has traveled a distance of 300 ft.
Question 2: What is the total acceleration of the car at the end of this 300 ft?
Note: Please provide equation and explain comprehensively and give step by step solution.
