The exercise involves calculating the acceleration of a car moving along a curved path. Below is a transcription of the relevant information and description of the accompanying diagram. ### Problem Statement The car is traveling at a speed of 30 m/s. The driver then applies the brakes at point A and thereby reduces the speed at the rate of \( a_t = \left(-\frac{1}{t}\right) \, \text{m/s}^2 \), where \( t \) is in seconds. ### Task **Part A:** Determine the magnitude of the acceleration of the car just before it reaches point C on the circular curve. It takes 15 seconds for the car to travel from A to C. **Requirements:** Express your answer to three significant figures and include the appropriate units. ### Diagram Description The diagram depicts a road segment with a curvature. The path is marked with three key points: A, B, and C. The following details are provided: - The angle at point B is \( 45^\circ \). - The distance from A to B is 100 meters. - The curve segment from B to C spans across a 5 meter wide section. The diagram illustrates the car traveling along this curved path, highlighting the braking process between points A and C. To solve the problem, use the provided initial speed, deceleration function, and time duration to compute the car's acceleration as it approaches point C.
