2*3.14*220 = d
v= d/t ( put d and t=51 )
a = v^2/r ( r 220 ).
Car traveling on circular track. Point A is at positive x,y. Point B is at positive x, negative y.
A car is traveling around a horizontal circular track with radius r = 220 m as shown. It takes the car t = 51 s to go around the track once. The angle èA = 31° above the x axis, and the angle èB = 56° below the x axis.
