The flywheel of a steam engine runs with a constant angular velocity of 180 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 2.6 h. (a) What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown? (b) How many revolutions does the wheel make before stopping? (c) At the instant the flywheel is turning at 90.0 rev/min, what is the tangential component of the...

Consider the DC motor-driven wheeled mobile robot shown in figure, in which m is the mass of the wheeled mobile robot, r is the radius of the driving wheel, and T is the torque delivered to the wheeled mobile robot by the DC motor. For simplicity, the motion is restricted to one spatial dimension. The figure also shows the simplified drive system, including the equivalent electrical circuit of the DC motor, the gears, and the driving wheel. The motor parameter...

Please answer all parts and show all work
11. (50 pts) A 4.0 kg mass is connected by a massless string to the rim of a pulley. You can assume that the pulley is a cylindrical shell has a radius of 0.50 m and a mass of 11.6 kg, as shown in the figure and that the string does not slip on the pulley. The mass is released from rest at a height of 2m above the ground. a. (10...
