Do not round intermediate answers. Give your final answer$($s$)$ to three decimal places. Check your units.

For the instant represented, car A has a speed of $115k\frac{m}{h}r,$ which is increasing at the rate of $4k\frac{m}{h}r$ each second. Simultaneously, car $B$ also has a speed of $115k\frac{m}{h}r$ as it rounds the turn and is slowing down at the rate of $4k\frac{m}{h}r$ each second. Determine the acceleration that car $B$ appears to have to an observer in car $A.$

$a\frac{B}{A}=$

$i\frac{m}{se{c}^2}$

$a\frac{B}{A}=$

$j\frac{m}{se{c}^2}$
