1. An DC shunt motor is connected with a wheel with 10 cm radius to a 50 kg weight, aiming to lift the weight. The motor is connected with a

wheel with 10 cm radius, r. The voltage induced across the rotor, Eo, equals 0.1 n, where n is the rotational speed in resistance is 1 Ohm.rpm.The rotor a) As the motor is turned on by connecting it to a 72 V battery, what is the initial acceleration of the weight? b) As the weight increases its speed, does it eventually reach a constant velocity or a constant acceleration? c) What is the numeric value of this constant acceleration or speed?
