the magnitude is 4.67 y component of the cars acceleration when it is at point A

Question

the magnitude is 4.67

y component of the cars acceleration when it is at point A is -4.23.

the x component of the cars acceleration when it is at point B is .I got -2.26 but i am not sure if it is negative or positive.

What is the y component of the cars acceleration when it is at point B.

the magnitude is 4.67 y component of the car acceleration when it is at point A is -4.23. the x component of the car s acceleration when it is at point B is .I got -2.26 but i am not sure if it is negative or positive. 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 acceleration is increasing constant decreasing

Explanation / Answer

Y component of acceleration at B = (v^2/r) * sin (theta b)

As theta b is decreasing after B , therefore sin (theta b) also decreases and therefore Y COMPONENT OF ACCELERATION AT B ALSO DECREASING
