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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Aplane slab absorbs neutrons from a nuclear reactor and experiences non-uniform internal heat generation something like q’’’(x)=q0exp(-5x/l). cooling is provided at x=0 by convection to a fluid at t∞ = 50 c, and the surface temperature is maintained at t(0) = t0. the back side of the slab, at x=l, is insulated. use an energy balance to find the value of the heat transfer coefficient required. use these numbers for the parameters: q0=1.4×107w/m3, t0=107 c, and l=100 mm. the thermal conductivity of the material is k=40 w/m-k.
