(Newton’s Laws, tension) A 300-kg horse is pulling a heavy 200-kg sled on a flat snowy ground through a rope connection and traveling with a speed of 5 m/s. The ground provides a force of 1300 N to the horse in parallel to the ground. The friction force on the sled is 150 N and no friction force acting on the horse. Find: (a) the acceleration of horse-sled system (b) the tension in the rope, PLEASE ANSWER ALL AND EXPLAIN...

The sliders A and B are connected by a light
rigid bar of length l = 0.37 m and move with negligible
friction in the slots, both of which lie in a horizontal plane. For
the position where xA = 0.29 m, the velocity of
A is vA = 0.84 m/s to the right.
Determine the acceleration of each slider and the force in the bar
at this instant. The acceleration of A is positive if to
