A scientific winch on an oceanographic vessel hoists a water-sampling container of mass 0.75 kg vertically through a height of 16.4 m.
Calculate the increase in gravitational potential energy of the container.
Gravitational field strength, g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg.
Use the equation:
ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp=m×g×Δh
