An archer draws his compound bow and shoots an arrow. The 23 g arrow leaves the bow with a velocity of 88 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the arrow through a displacement of 57 cm.

You have a pair of cannon balls, each 100kg in mass, and a 'charge shuttling' device which can be used to remove electrons from one object and place them on another. One of the cannon balls is suspended from the ceiling with an insulating cord.

Cold water (cp = 4180 J/kg·K) leading to a shower enters a thinwalled double-pipe counterflow heat exchanger at 15°C at a rate of 1.25 kg/s and is heated to 60°C by hot water (cp = 4190 J/kg·K) that enters at 100°C at a rate of 4 kg/s.

Determine the magnitude of the acceleration for the speeding up phase.
