Question:

A/m garden hose with mass 4.4 kg is coiled up on the ground and a distance 35.4 m from your garden. You pull on one end of the hose with force of magnitude 1 5. 7N in a single direction. You continue to pull until your end of the hose is at the edge of the garden. h is very reasonable to note that the hose is very thin compared to its length, and as a first approximation, assume that the hose straightens out to its total length

Part (a) What is the speed of the hose in m/s as you reach the garden, neglecting friction?

Part (b) What is the change in energy of the hose in joules?

Part (c) What is the change in internal energy of the hose in joules?

Part (d) The hose is rather stiff and energy must go into forcing the material to flex. If the material of the hose has a specific heat of 3.2 kJ/kg °C, what is the change in temperature of the hose in 'C
