A long, straight wire of radius 0,1 m carries a steady current 3 Ampers that is uniformly distributed through the cross section of the wire. The magnetic field at distance 0.32 m from the center of the wire is x 10-7 T.​

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
