**Problem Statement:**Determine the time needed for the load at "B" to attain a speed of 15 m/s, starting from rest, if the cable is drawn into the motor with an acceleration of \( a_A = 0.6t \, \text{m/s}^2 \) where "t" is the time in seconds.**Diagram Explanation:**The diagram shows a pulley system with a motor driving a wheel at point "A." The cable from the motor pulls a load at point "B." The velocity of the motor is indicated by \( v_A \) and the velocity of the load is indicated by \( v_B \). The motor accelerates the cable, causing the load to move upwards.**Solution:**The task is to calculate the time "t" when the load "B" reaches a speed of 15 m/s, given the acceleration \( a_A = 0.6t \, \text{m/s}^2 \).**Answer:**The calculated time is \( t = 14.14 \, \text{s} \).

As indicated in the illustration, two blocks are connected by an inextensible cable. Block A weighs 178.6 kg, while B weighs 252 kg. If the system is released from rest, calculate the acceleration (in m/s2) of block B. For simplicity, let us suppose that the coefficient of friction between block A and the plane is μk = 0.24 and that the pulley is both weightless and frictionless. Make use of the formula g = 9.81 m/s2.
