Boxes a and b are descending vertically supported by a parachute .
Box A has mass of 60kg Box B has mass 45kg and hangs from box a by means of a light vertical wire. Air resistance on the boxes is neglected.
At one stage the boxes are slowing in their descent with the parachute exerting an upward vertical force of 1120 N on box A. The acceleration of the boxes is a ms-2 upwards and tension in the wire is T newtons.
Write down separate equations of motion for box a and box b?
Calculate the acceleration and the tension in the wire?
Draw a diagram showing all the forces acting on box a and box b?
