) A 2.5 in diameter through hole is to be cut in a block of Copper(1) by electrochemical machining. The block is 2.0 in thick. To speed the cutting process, the electrode tool will have a center hole of 2.25 in, which will produce a center core that can be removed after the tool breaks through. If the efficiency of the ECM operation is 90%, what current is required to complete the cutting operation in X2 minutes?

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
