A uniform rod AB, 4m long and weighing 12 kg, is supported at end A, with a 6kg lead weight at B. The rod floats as shown in the figure with one-half of its length submerged. The buoyant force on the lead mass is negligible as it is of negligible volume. Find the tension in the cord and total volume of the rod.

A lift ascends from rest with uniform acceleration of 4m/s^2, then it moves with uniform velocity and finally comes to rest with uniform retardation of 4m/s^2. If the total distance covered during ascending is 28m and total time taken for ascending is 8s respectively. Find the time for which the lift moves with uniform velocity .Also find its uniform Velocity.
