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.
