Will give up vote if all parts are answered and explained infull detail. Thank you.
7.(12 points) A car is traveling around a horizontal circular track with radius r = 435 m at a constant speed y = 78 m's as shown. The angle PA = 23° above the x axis, and the angle Og = 56° below the x axis. A) As the car passes point B, the magnitude of the y-component of its acceleration is A increasing B. constant C. decreasing B) What is the magnitude of the car's acceleration? c) What is the v component of the car's acceleration when it is at point B?
