A car is traveling around a horizontal circular track with radius r = 250 m as s

Question

A car is traveling around a horizontal circular track with radius r = 250 m as shown. It takes the car t = 64 s to go around the track once. The angle ?A = 31° above the x axis, and the angle ?B = 63° below the x axis.
2)What is the x component of the car’s velocity when it is at point A

3What is the y component of the car’s velocity when it is at point A

4)What is the x component of the car’s acceleration when it is at point B

5)What is the y component of the car’s acceleration when it is at point B

Explanation / Answer

2) VAx = -r*w*sin(31)

= -250*0.098125*sin(31)

= -12.63 m/s

3) VAy = r*w*cos(31)

= 250*0.098125*cos(31)

= 21.03 m/s

4) VBx = r*w*sin(63)

= 250*0.098125*sin(63)

= -21.86 m/s

5) VBy = r*w*cos(63)

= 250*0.098125*cos(63)

= 11.14 m/s
