can you please help me

A car is traveling around a horizontal circular track with radius r = 210 m at a constant speed t = 50 s to around the track once. The angle theta A = 28 degree above the x axis, and the angle theta B = 64 degree below the x axis. What is the magnitude of the car's acceleration? What is the x component of the car's velocity when it is at point A What is the y component of the car's velocity when it is at point A What is the x component of the car's acceleration when it is at point B What is the y component of the car's acceleration when it is at point B As the car passes point B, the y component of its velocity is

Explanation / Answer

v=2pi*r/t=26.38

mag of aan=v^2/r=3.32

at A

xcomponent=-3.32cos28=-2.93m/s^2

y compo=-3.32sin28=-1.56m/s^2

at B

x compo =-3.32cos64=-1.45m/s^2

y compo=3.32sin64=2.98m/s^2

6.decreasing
