An electric car is designed to run off a bank of 14.0-V batteries with total energy storage of 3.00 × 10 7 J. If the electric motor draws 7 000 W, what current will be delivered to the motor?

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
