A car is traveling along a straight highway with a speed of 72 kph (20 m/s) when the driver suddenly applies the brakesjust before entering the curved section A-B, REDUCING its speed at a constant rate until it reaches point B. The 90-mlong curved section A-B has a constant radius of curvature r. An accelerometer mounted on the car recorded a totalacceleration of 1.74m/s² just before the car passes point B.B.I 061. Which of the following is FALSE regarding the car's motion along the curved section A-B?Its velocity is decreasing and is tangent to its path.Its tangential acceleration is tangent to its path.Its acceleration is increasing in magnitude.Its normal acceleration is directed towards the center of curvature of the path.
