A wheel has a constant negative angular acceleration (deceleration) of - 5 rad/s2. At the end of time interval t = 7 s, the wheel is found to be moving at 116 rad/s. What was the initial angular speed of the wheel? Please round your answer the nearest whole number (integer).A uniform disk, with mass M= 8.0 kg is mounted on a fixed horizontal axle as shown below. A block with a mass m = 1.0 kg hangs from a massless cord that is wrapped around the rim of the disk. The block is released from rest. What are the (a) acceleration of the falling block and (b) the tension in the cord. M T
