16. Two blocks respectively A weighs 16OON and B weighs 2400N are connnected by a spring both rests on an inclined plane upward to the right at a slope of 3 vertical to 4 horizontal. Their motion is down to the incline and resisted by a force P = 800N. Their coefficient of friction is 0.30 under A and 0.10 under B. Compute the force in the spring.
