A load of bricks with mass m1 = 14.4 kg hangs from one end of a rope that passes over a small, frictionless pulley. A counterweight of mass m2 = 27.8 kg is suspended from the other end of the rope, as shown in the figure. (Figure 1) The system is released from rest. Use g = 9.80 m/s2 for the magnitude of the acceleration due to gravity. (a) What is the magnitude of the upward acceleration of the load...

A 3.70 kg mass is observed to have a constant acceleration from an initial velocity of 2.44/m/s to a final velocity of (18.9/-10.7 j) m/s in 2.91 s. Two forces act on the mass: gravity (F_G = -36.26 j N) and an unknown applied force F. Determine the acceleration and unknown force.
