The ywheel of a steam engine runs with a constant angular velocity of 160 rev/min. When steam is shut off, the friction ofthe bearings and ofthe air stops the wheel in 2.4 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 theywheel is turning at 80.0 rev/min. what is the tangential component of the linear acceleration of a ywheel particle that is 34 cm from the axis of rotation? {d} What is the magnitude of the net linear acceleration of the particle in {c}? (a) Number i -1.9392547 Units rev/min"2 v (bl Number i 1152 Units rev v (c) Number Units ll ll (d) Number Units
