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

Train A travels with a constant speed $v_A=140k\frac{m}{h}r$ along the straight and level track. The driver of car $B,$ anticipating the

railway grade crossing $C,$ decreases the car speed of $95k\frac{m}{h}r$ at the rate of $5\frac{m}{se{c}^2}.$ Determine the velocity and acceleration

of the train relative to the car.
